The release also offers codec support for decoding struct container fields as either map or document types, rather than an ancestor type. Additionally, the mongo package will support a closed approach for checking transaction error labels. For more information please see the 1.11.4 release notes.You can obtain the driver source from GitHub under the v1.11.4 tag.`Documentation for the Go driver can be found on pkg.go.dev and the MongoDB documentation site. BSON library documentation is also available on pkg.go.dev. Questions and inquiries can be asked on the MongoDB Developer Community. Bugs can be reported in the Go Driver project in the MongoDB JIRA where a list of current issues can be found. Your feedback on the Go driver is greatly appreciated!Thank you,The Go Driver Team",

The trick is to make sure you have all the necessary dependencies installed and configured correctly.Make sure the react-native-fetch-blob library is installed for files I/O operations, as this will alleviate any issues caused by problems with file permissions or overwriting existing files. You might also need to install an async library like redux-thunk in order to process fetch requests asynchronously.Finally, verify that your code runs without error before running it on device by using Jest for unit tests. Taking these steps should help you troubleshoot the app crashing while read/write operation in React Native.P.s - I’m Aliena Jose works as a app developer at Techmango, React native app development company",

Thus, it may be beneficial to work from the required queries first, making it as simple as possible, and then let the schema design follow the query pattern.\nReading from your description, I think that you can create a data model where the database name is the name of the school and then this database has different collections like- students, teachers, administrative staff, etc and within these collections, you add the details of the corresponding entity:This would also help in faster reads and writes since one school would want to read and update records related to their students only.\nOr if there are just students’ record in your database, then you can model it by having a database and having separate collections for each school and for each collection, having the students’ documents corresponding to that school collection.Ultimately, as mentioned earlier, it would boil down to the queries that you are intending to use in your application. You can use mgeneratejs to create sample documents quickly in any number, so the design can be tested easily.Regarding creating collections and documents in MongoDB, you can refer to this guide: Create a CollectionI’m also attaching some more resources that you might find useful:\nModel Data Model Design\nMongoDB Fundamentals FAQsHope this helps.

"text": "Hey @Mohamed_Abdillahi,Thanks for the reply.The approach you described seems a bit tricky to me. One suggestion I would give is to name your collections starting with the name of the school and then the entity that you want to include in that collection, ie.:With this approach, you can use lookup operator when needing to search across many collections of the same school.It has collections where the collection name is the same as the school username. Every collection/school has subcollections like students, teachers, classes, etcYou can also do this by creating a students and teachers etc collection, then in the documents, specify the school name, ie. keep a field named School in the documents itself. This way, your student document might look like this:and similarly, you can store a school field in your other collections too like teachers, staff, etc.By the first approach you mentioned, the database name isn’t same as the school name. There is only one database.I still didn’t get why keeping different schools as different databases can’t be done. Is there any particular reason why we are dismissing this thought? With this approach, it would look like this:\nDBs516×738 22.1 KB\n\nSchool_1, School_2, etc are the databases’ names. And within them are your collections of students, teachers, etc. You can switch between different databases using the use <db_name> command. If you have any doubts about how to create or use multiple databases or collections, you can go through the following documentation: Databases and CollectionAs you can see, there are many approaches that you can use while designing your model. I would suggest you explore all the alternatives before deciding there has to be only one database or limit your other options.\nA general rule of thumb while modeling data in MongoDB is that things that are queried together should stay together.

"text": "Hello @Greg_Guy ,Welcome to The MongoDB Community Forums! Based on the provided code and logs, it seems that the connection to MongoDB is being established successfully and there are no errors reported. I think your code looks like in hang state because the connection was never closed.However, I noticed that you are not using Promises and client.close() statement to connect or to close the already opened connection. Below blobs are from documentation regarding PromisesPromisesA Promise is an object returned by the asynchronous method call that allows you to access information on the eventual success or failure of the operation that they wrap. The Promise is in the Pending state if the operation is still running, Fulfilled if the operation completed successfully, and Rejected if the operation threw an exception. For more information on Promises and related terminology, see the MDN documentation on Promises.If you are using async functions, you can use the await operator on a Promise to pause further execution until the Promise reaches either the Fulfilled or Rejected state and returns. Since the await operator waits for the resolution of the Promise, you can use it in place of Promise chaining to sequentially execute your logic. For additional information, see the MDN documentation on await.Below is an example on how you can use such syntax and you may update the same as per your requirementsThis code uses async/await to wait for the client.connect() method to resolve before proceeding with the rest of the code. The try/catch block is used to catch any errors that may occur, and the finally block is used to ensure that the client.close() method is called, regardless of whether an error occurred or not.I hope this helps resolve the issue with your code hanging.Regards,\nTarun",

It acts as a layer that translates queries and data between a mongod or mongos instance and your reporting tool. The BI Connector stores no data, and purely serves to bridge your MongoDB cluster with business intelligence tools.Note: As an alternative to using third-party data visualization tools and the BI Connector, you can use MongoDB Charts to create data visualizations directly from your MongoDB collections.For more information, please checkRegards,\nTarun",

When someone hits a problem, we were around to help.Now, the labs are lost to anyone who completes a stage in the lab, step by step.there is no going back, no reset/restart, no redo, or no replay. That is it. Even the resources used in them are lost if a developer “decided” otherwise.When someone hits a problem, they need to get the attention of an employee which is a limited official human resource. But since Learn is a “free” resource, it is not always easy to get that attention. (if it was a paid service we could squish immediate help, right?)In other words, Labs are no more a part of the “community”.In order to make things right (ok, at least “right” as in the sense of “community”), Labs should be accessible after their completion for the community to supply their help.At least, a “reset lab” option to start fresh would benefit a lot. even though it would require completing steps again, we could test and see any problem at any step (and on any browser) as the community. I am sure you may come up with a better solution, or just do this and allow us to “reset” the labs.I hope you implement this change pretty soon for the sake of the community.",

"text": "@DomC as some things were brought to my attention from elsewhere, (Not MongoDB, barely ever talk to anyone from it these days) I just want to be clear I am not employed by MongoDB, nor sponsored by it. Separation from MongoDB was back in end of Nov due to fictitious drama from someone external to MBD that I won’t get into here.But in large I am very objective when it comes to MongoDB or any company for that matter, I just want to make it clear I’m not white knighting, nor am I worried or afraid of producing criticism or opinions about products or services, or actual known public facts. (Much of the time I wait until someone else exposes a problem I found previously before talking about it.)In relation to your GraphQL that I’d like to make clear, yes, there are a lot of functionalities that aren’t supported, despite Apollo GraphQL fully supporting it. Yes, I can see where you can feel it isn’t production ready, in some aspects I do agree with you and on other aspects I have to heavily disagree. Because you should not be focusing on just GraphQL to secure your environment, nor should you be making Atlas itself the core focus of securing your environment.Security is a culture, not a product. You need to make sure that you firmly understand that, in which your database is only one layer of the onion whether the feature is organic to it or not, there is always other ways to implement what you need.This is coming from someone who’s worked on NIPRNET and SIPRNET networks and applications, who’s also worked on and developed applications used I can’t even discuss or go into specifics of that are used in high security environments.I’ve also worked on penetration testing tools, RATs, vulnerability assessment tools, even reverse engineering tools to identify and break down an application to its machine code functionalities from compilation for exploitation.When I say this, I do mean it. You will never have a fully secured environment, and there will always be a security vulnerability that you need to make the conscious effort to either accept the liability or mitigate the threat.You also need to make stronger efforts besides password/email auth to really evaluate whether an application or service does, or can meet your applications needs. Coming from someone who’s assessed many applications for various reasons, even when people were panicking Seagate Harddrives had spyware built into them, you’re talking to one of the men who evaluated whether or not the situation was hyperbole. I also know the security team from the Air Force that handled the Ukraine power plant hack, and later worked in the evaluation of vulnerabilities and root causes of what allowed it to be breached in the first place. That’s my name among several in the report to Congress in 2016, and the report given to the EU by the company I contracted with when I say this.If you would like help in working out the needs requirements for your application, and mitigations that could potentially workout what services may help you out, just let me know as I don’t mind. But “Atlas with GraphQL makes Brute forcing easy.” isn’t entirely accurate as you’re focusing on a server authentication and login error count without a handler. Which if MongoDB did implement said kind of handler feature, you then need to work on, and ensure it’s in sync with your SSO/LDAP/ETC. systems. Have a way to handle or mitigate false positives, and so on. Which honestly, your SSO solution, not Atlas should be responsible for that, but that’s just MHO.And I would have edited and added this to my other post, but for some reason the edit button disappeared early?

However, this seems to be disallowed, as the PublicUser is a linked collection. To set up the subscription, all I need is the ID, which is exactly what is stored in the database itself. But Realm only sees a link, as far as I can tell, and there is no way to use the ID itself when establishing a sync subscription.To get around this, I can duplicate the ID in a separate field, egThis duplication allows me to establish a subscription on the basis of the creators ID. I plan on using this approach, but I wanted to make sure that I am not missing some way to simply look at the link as an ObjectId rather than a Link, as it would be much cleaner.

Addresses were separated from phone numbers, and SSNs were separated from names and addresses, names were held separately from address and phone numbers and SSNs, their purchase histories were all separate and so on.So the internal, non-displayed ID is what tied everything together for any one user. This also helped with a CDC audit due to COVID to determine how many and who were at location Y, I could provide the CDC with the exact info requested for my friends app, instead of giving them all of the users info.It actually made things a lot easier, same goes for his bookkeeping.

Same with just deleting the document on the local client because it’s something going on with the writer processes and the server not completing the upload/write/syncing.By terminating sync, AFTER client reset logic is in place to keep unsynced documents this issue is corrected once sync is re-enabled.It won’t make a difference if you delete the doc locally, or on server at all, because it will not abort the “upload” even if the writer doesn’t even see it.It’s only when the term and resync happens that the upload is aborted, and upon resync the new version of the document makes it to be synced, again to reiterate, a term and resync is the only thing you can really do in this situation for the reasons outlined.",

Because the Great Firewall of China has serious restrictions your app is going to have to meet.They would be the go-to for anything app deployment related, but as far as hosted services go Alibaba does host and service MongoDB, you can also run Apollo GraphQL servers within Mainland China or on Alibaba virtual infrastructure, and then route the appropriate GraphQL clients on the mobile apps.MongoDB may launch Realm/Device Sync on Alibaba, but that’d yet to be determined. You can also establish HTTP and JSON based APIs and run them to the Alibaba hosted MongoDB instances as well. There’s a myriad of ways to ensure data gets from mobile to the cloud that way.But again, prior to you launching your app, I’d highly encourage that you communicate with 中华人民共和国工业和信息化部 and get a solid, approved-in writing guide out, be sure to explain you’re looking to comply with Chinese law, what the app is, what it does, why you’re making it, and why you want to deploy it across mainland China and the consumers there, as well as what private information of Chinese citizens will be recorded, and what will happen to that data.The PRC (People’s Republic of China) takes foreign software to serious extremes in what they view as security or safety risks to protect PRC citizens from what they may perceive as a threat to the public. You need to be sure to navigate those waters prior to committing to any services, however if you do need help navigating how to get in contact with 中华人民共和国工业和信息化部, you’re welcome to DM me your business contact e-mail and I can walk you through the steps and processes. I’ve worked on, launched, and deployed 11 mobile apps that operate within China, Vietnam, Siam (Thailand, just some still know it as Siam), and Myanmar. All of which are still operating today.Again, you need to focus more on being highly respectful to any requests or wishes by the PRC Government, and make it clear that’s why you’re reaching out to them, and why you want to launch your app and they will be more than happy to help, but they will have requirements of things that will have to be implemented within the applications versions that will be operational and available to the Chinese public.EDIT:@Alvin_ChanAlibaba Cloud ApsaraDB for MongoDB is a secure, reliable, and elastically scalable cloud database service.MongoDB does support the above, but am unsure if you would pay for support directly with Alibaba, or if it’s direct with MongoDB.There is the OpenAPI by Alibaba that can link your mobile app to the MongoDB hosted in Alibaba.SDK中心是阿里云OpenAPI开发者门户支持9门SDK语言的主要平台，为每种SDK语言提供demo、完整工程、部署指南、调试平台和场景化示例。You would need to select the correct SDK for you, etc.It’s known when or if Alibaba will also host Realm/Device Sync, but I’m sure they may cook something up in time.",

Or things can get extremely ugly and overly problematic, as they also will go through local governments. It took almost a year to clear things up and get rid of labels a client company I worked for was an espionage platform to overthrow the Junta. That labeling for my client had intense ramifications in dealing with other governments in the region to allow the apps deployments.India is also an interesting process, just to be aware of.South Korea was probably the best experience to handle if your company is US Based, or if it’s based in Singapore. Japan probably had the strictest user data compliances Ive ever seen from any nation in that region, even down to when data had to be destroyed related to a consumer if that consumer hasn’t accessed the app in so long.That said though, in the Far East Asia landscape AWS is everywhere, it’s also in Beijing, but I haven’t seen Realm offered out off Beijing.

Also, as per the JIRA ticket - the Go driver does not cache DNS and instead relies on the OS and its resolvers.So if the IP is stale, the DNS cache is the possible issue as it could be in the OS, network, etc.Furthermore, if you are looking to integrate the search solution into the MongoDB Atlas Dataset, I’ll recommend using Atlas search for better compatibility and using the combination of three systems database, search engine, and sync mechanisms into one, delivering application search experiences much faster.For more information, please visit the MongoDB Atlas Search documentation.Best,\nKushagra",

"text": "Hi @Max_Dudzinski,Thanks for sharing the details.As per the shared information,I believe the reason why the driver cannot reconnect to the new host is that the replica set was configured with the actual IP address instead of using a hostname as per the recommendations in the documentation.This is because if you use IP addresses, any changes in the IP address of a member will require updating the configuration file of all other members, which can be time-consuming and error-prone. On the other hand, if you use a DNS hostname, the IP address of a member can change without requiring any configuration updates on other members.For example, If you use hostnames like member1.example.com, member2.example.com, and member3.example.com to configure a MongoDB replica set, any changes in their IP addresses will be automatically resolved by DNS without needing to update the configuration file.To resolve this - I will recommend you change the config of your replica set to use hostnames instead of IP addresses.For detailed information please refer:I hope it helps!Best,\nKushagra",

"code": "rs.status()",
"text": "@Max_Dudzinski thanks for all the information, this is a really interesting problem! There is actually a section from the MongoDB driver specification that describes the expected behavior of drivers under similar circumstances, and some rationale for those decisions:…An alternative proposal is for clients to continue using the hostnames in the seed list. It could add new hosts from the hello or legacy hello response, and where a host is known by two names, the client can deduplicate them using the “me” field and prefer the name in the seed list.This proposal was rejected because it does not support key features of replica sets: failover and zero-downtime reconfiguration.In our example, if “host1” and “host2” are not reachable from the client, the client continues to use “host_alias” only. If that server goes down or is removed by a replica set reconfig, the client is suddenly unable to reach the replica set at all: by allowing the client to use the alias, we have hidden the fact that the replica set’s failover feature will not work in a crisis or during a reconfig.…Basically, MongoDB drivers connect to the replica set nodes as described by the replica set (i.e. the information that rs.status() returns) because they depend on timely and accurate topology change info from the MongoDB replica set to support “failover and zero-downtime reconfiguration”.When a driver has completely lost connection to a replica set, there are two possible circumstances:Drivers could simultaneously attempt to connect to the last known MongoDB replia set and re-initialize using the connection string to see which succeeds first. However, that may not always be the best behavior for all use cases, so we have historically assumed case #1 (the more common case) and required users to implement their own recovery logic for case #2.Another section from the specification seems to suggest that using arbiter nodes can help with the case where all replica set members are moved in a short period of time:… in the rare case that all data members are moved to new hosts in a short time, an arbiter may be the client’s last hope to find the new replica set configuration.Do you have the option of running arbiter nodes that could help the Go driver keep track of the replica set node after it is moved? If not, it sounds like your solution to detect the error and reconnect is the correct solution.",

If it can handle it, it’s should be ok. If it cannot, then you might see some issues with it.I would suggest you to experiment with some example workloads to start with, and see if the hardware can keep up with demand.Best regards\nKevin",

"text": "Thanks for providing those details Brian. Firstly, I’m not sure of all other requirements here but based purely off the sample documents and information provided, it may be possible to obtain the second table assuming the first table is a collection where the atlas search index exists.In my example below for the student with a first name of \"Elizabeth\", I have just added an \"assessment\" field which contains the score for a particular assessment. This is not what I am recommending the schema to be and is only for demonstration purposes for Atlas search (and in particular, the compound operator, the text operator with fuzzy and synonyms options used).Sample documents used in the test:I am using a default Atlas Search index (named the \"scores\" index) but have defined Synonym Mappings. For the synonym mappings, I’ve created the \"nameSynonyms\" mapping below:Assigning \"Elizabeth\" to variable \"queryFirstName\" and details of the $search portion of the pipeline (assigned to var a):Output (removed \"_id\" for brevity):I presume the question here was more based off identifying duplicate names using $search. How you uniquely group and identify a student is a different matter. Hopefully the above example provides a bit of help in determining if this works for your use case.You may wish to consider cleaning duplicates prior to them being entered into MongoDB if possible. This may assist with inaccuracies that may appear with the above method (for example - consider if an entry had the first name “Lizx”).Regards,\nJason",

"text": "Hello,\nI am currently evaluating Atlas Device Sync for a mobile app with respect to GDPR requirements for a German company.\nThe data that should be synced is non-personal, but it seems that the Atlas Sync service itself collects personal identifiable data like the client’s IP address or device identifiers.There are two solutions that came to my mind, in order to prevent personal data from being send to MongoDB:\n1: Encrypt Atlas with a custom KMS key, that my company owns. Does this encryption include metadata (like the IP) from Atlas Device Sync?\n2: Proxy the connection between the device and Atlas and remove the client’s IP address before it reaches Atlas. Is this possible? How can I configure a custom URL in the Realm Sync Configuration?I would appreciate your thoughts and ideas on that topic. Thanks in advance.",

"text": "Hello @Markus_Kieselmann I hope someone already answered this at least externally to the forums.Basically Device Sync is in fact compliant for GDPR, you can find all the things it’s compliant for here: Trust Center — MongoDB Cloud Services | MongoDBIt even recently got CJIS and a higher level of FedRAMP certification, too. I’m not sure at what level CJIS is for Atlas, but it exceeds Interpol’s RPD and CCF requirements, meaning it well exceeds GDPR compliance requirements, it’s going to come down to how YOU choose to design the collections and infra around it.The FedRAMP is also heavier than Germany’s BDSG, you could probably talk to the provisional authorities in your region of Germany even, about a German Government Atlas instance if enough manpower were available etc. You never know, and honestly I’m sure MongoDB wouldn’t mind said kind of conversation.When I worked with NATO back in 2012 I know Atlas and Firebase were both infrastructure that would have been amazing to have had available. But without the special stuff involved with FEDRAMP and CJIS, it still is GDPR compliant just on its own accord in a stand alone constraint, it’s even HIPAA compliant, which HIPAA exceeds needs of GDPR, and is marginally even more strict than GDPR, which also exceeds the CFRA and other consumer data privacy acts.That said, in Atlas the data is locked away from even employees unless exclusive circumstances and permissions from the customer directly are given for emergency situations.And to prevent data from being transferred to MongoDB in the states? The data is local to the regional datacenter you choose. If you pick Frankfurts DC, that’s where the data is, which is ran and operated by German’s.Amazon FRA50 Kleyerstrasse 88-90. Frankfurt am Main 60326 is the Atlas Datacenter in Germany, hosted by Amazon, manned by German born citizens, which you could always reach out to Amazon directly for any specific restrictions you need to have in place, and communicate that with MongoDB for what’s needed.Given MongoDB is GDPR compliant, I honestly wouldn’t worry as much about that.EDIT\nAnd hey @Markus_Kieselmann, if you’re needing NATO compliance I do have the contact information for the Joint Information Security, Systems, and Data Command out of Ulm, as well as NCISG out of Mons, in the Joint Support and Enabling Command Headquarters. I do have the direct lines if you need questions answered of what AWS services and third party services are approved.Which the Datacenter Europe Central - 1 regions 50, 53, ETC. are all approved datacenters, they do have channels within Amazon you can be directed through if you’re asking because of a NATO need. If this request of info isn’t related to NATO, you can freely just use the general consumer Atlas and normal AWS channels and be GDPR compliant based upon your configurations and what data you choose to collect.",

"text": "@Markus_Kieselmann if you see this, just to let you know I reached out to some of my contacts in Germany and whether Atlas or Realm can be used for GDPR sensitive items.Realm was deemed acceptable per BDSG guidelines, and is acceptable enough to meet the needs of the 2021 Cyber Security Strategy, but is not approved for military or militia use as per Heer’s publication for Germany’s KdoCIR, who also had findings determined Realm was not a threat to Germany’s consumer population.Germany as a nation has the means to lock down foreign internet traffic to and from any mobile application on any devices not using a Germany sourced SIM card. Or geographically lock access to the application. This would be done by the BND.Do note a caveat to this, is that MongoDB support personnel are not located in Germany, so doing this would lock out MongoDBs ability to directly provide support to your mobile applications Realm infrastructure. But still maintain access to your company and its services, but I’m sure you could work something out with MongoDB.KdoCIR Is experimenting with Realm like it is other systems like it, but there’s no comment on whether or not the Heer will adopt Realm, or consider how to develop their own version of it.EDIT\nAlso under the Verbandssanktionengesetz, MongoDB cannot put in place efforts to undermine GDPR within Germany, or it can violate the EU international laws, and Germany’s laws which would bring in the US State Department, and DoJ. Basically that means MongoDB as an American Company can face very scary people in the US Government who can push very severe punishments domestically, in addition to EU company sanctions should they violate international laws.Simply put: All of this in summary, I wouldn’t have GDPR concerns when even the German Government has approved its use, and it’s used presently in a postal application to deliver and track mail, with potential other areas of the German government may formally use Realm pending stability fixes.",

This is what we can see in the mongo logs:These log lines should help:Aftrer those, mongodb is down…I have found some really similar issues in this forum, but it was not the same. For most of them, the problem was “no space left on device” but in this instance, we have plenty of space (and we do not have that line in the logs). The only way to fix this so far is to restart mongd service.Thanks in advance for any kind of help!",

MongoDb has no documentation on testing and if you use the recommended way to write to the database (Realm.write) you will inevitably end up with a bunch of deadlocks in your tests. There doesn’t seem to be a way to override the default write dispatcher in your tests. I ended up using a custom write function that calls realm.write in production but realm.writeblocking in tests.3: Database objects are no longer automatically updated. This is nice once you get the hang of it, but can lead to significant rewrites in your viewmodelsIn general I think the transition will be worth it for me. The new SDK makes it easier to use coroutines and I am much more confident regarding threading than before. The code base is simpler and more consistent. For larger apps/organizations I am not sure if the migration path I took is feasible since it will completely break your app for a long long time, so make sure to have a strategy before doing the migration.",

So your users are unaffected.Then, when you’re done working on the Flexible sync version of your app, merge it and replace the old app using Java with your Kotlin version. Then the users who already have your app downloaded will download a “big update,” and not be the wiser at all what happened.Then on Atlas before this, migrate all the data from one collection to the new collection, make it all the same and drop the old collection after you’re done pushing the Kotlin version of your app, and no one will ever be the wiser via user base that anything happened.

Looking at the deleteUser function in the RealmDatabaseManager, I am not seeing anything being done with the array when a user is removed.In other words if Realm has three usersuser_0\nuser_1\nuser_2which is a .count of 3, and user_1 is deleted, the collection would have a count of 2 - so all is good.However, the Array that contained those elements would still have a count of 3 - causing a crash as the iterator is attempting to access an object that no longer exists.Two possible fixes:1 - When deleting the object from Realm, also delete it from the Arrayor preferably2 - return Realm Results object instead of the array - the Results object always reflects the status of the underlying data.I could be incorrect here but in our experience, casting Realm collections to Arrays is always a red flag for us.",

"text": "Aggregate count by value in Mongo Charts is a useful feature for visualizing data in MongoDB. To use this feature, you’ll first need to create a chart in Mongo Charts that is based on a data source containing the values you want to aggregate. Then, select the “Aggregate” option from the “Data” dropdown in the chart configuration panel. In the “Aggregate” panel, you can specify the field you want to aggregate by selecting it from the dropdown menu. You can then choose the type of aggregation you want to perform to remini, such as a count of the number of occurrences of each unique value. Finally, you can customize the appearance of your chart to display the aggregated data in a way that makes sense for your needs. With this powerful feature, you can quickly gain insights into the distribution of values in your MongoDB data and use that information to make informed decisions about your business or project reels",

When this happened, even though primary node was up and running, my entire application became slow in processing the transactions.My application basically reads message from Rabbitmq and my application internally has multiple modules which communicate via ActiveMQ. When the Secondary node gone down, my app throughput reduced from processing 500 Messages per second to 50, 60 or 100 Message per second. Even some time totally idel.

Although this deployment is supported, there are some caveats with regard to operations and maintenance.\nThe recommended way here would be to have a PSS architecture, with no arbiters unless compulsory for the deployment.Also, the version you are using, is quite old(Almost 6 years ago), I would recommend you to upgrade to the latest version with bug fixes and new features added.To add here, the error No Route to Host could be one of the reason for networking issues in the deployment.\nCould you help me understand how the replica set was configured or how the secondaries were added?When the Secondary node gone down, my app throughput reduced from processing 500 Messages per second to 50, 60 or 100 Message per second.As mentioned in the MongoDB release notes documentation:Starting in MongoDB 3.6, MongoDB enables support for “majority” read concern by default.What we suspect in your case, when the secondary node goes down, the majority commit point (information about the latest version of the data in all data-bearing nodes) cannot move forward due to the unavailable secondary. Consequently, the primary needs to keep old versions of data as long as the secondary stays offline. This will lead to a cache full scenario, where WiredTiger will spill it’s cache content to disk in the form of WiredTigerLAS.wt file in the dbpath.Can you confirm is you can see larger size of the WiredTigerLAS.wt file? Also, can you try disabling the majority read concern and see the similar issue.\nThe server ticket here mentions the similar behaviour in the past releases.Let us know if you have any other concerns.Best regards\nAasawari",

While this is still a significant number of documents, it may not necessarily indicate a major performance issue on its own. However it’s possible that the query cannot be made more selective, so it’s important to focus on optimizing other aspects of the query.Note that the shard key txnDate is not the prefix of the index used for the query.Furthermore, to gain a better understanding of the issue, please provide the following information:Best,\nKushagra",

"text": "Hi @MERUGUPALA_RAMES,Thanks for sharing the information Note that the shard key txnDate is not the prefix of the index used for the query.I think this indexis not very efficient for this particular query because the shard key txnDate is not the prefix of the index.It is important to choose a shard key that is frequently used in queries and ensure that it is the leading element of the index to leverage the full benefits of sharding. Please refer to the Shard Key Index for more details.If you need further help, can you please share the explain db.collection.explain(‘executionStats’) output, and the output of db.collection.getIndexes()?Best,\nKushagra",

Retrying in 60 secondBased on the logs you provided, it seems like the Backup Daemon is waiting for a system upgrade to complete before it can start. This could be due to a variety of reasons, such as missing dependencies, configuration errors, or incompatible versions of MongoDB or Ops Manager.As you are working with MongoDB Ops Manager and MongoDB Enterprise Edition. I would recommend you open a support case at MongoDB Support Portal as they have the required expertise and could help you with Root Cause Analysis and provide best solutions as per your use-case.Regards,\nTarun",
