"text": "Thanks for providing the details requested @franck_ishemezweUpon further inspection, it may be possible the error that’s being returned is due to the upsert behaviour as mentioned in the Upsert with Operator Expressions documetation:If no document matches the query criteria and the <update> parameter is a document with update operator expressions, then the operation creates a base document from the equality clauses in the <query> parameter and applies the expressions from the <update> parameter.I believe due to the query criteria, the \"price_detail\" field is of type object rather than an array when it is created as part of the “base document” which will then cause the error when the $push operator is applied.If it suits your use case, would it be possible for you to utilise $elemMatch at the query portion? The below example is performed via mongosh:You can alter your current update_one() method accordingly with $elemMatch although this would only be if it suits your use case as I understand your current <query> within the update operation is checking for if the \"price_detail.fuel_name\" and \"price_detail.fuel_id\" separately regardless if they exist in the same object within the array. It is highly recommended to test thoroughly on a test environment after making the required changes to verify it suits all your use case(s) and requirements.Regards,\nJason",

In case you couldn’t attend here’s the event summary:It was great to see Topcoder and MongoDB Communities as well as teams coming together to put together an event with some exciting workshop sessions, informational sessions as well as an inspiring story of S Deepak Kumar 's grit and passion who coming from a very small village in India, self-taught himself programming and won a global hackathon.\nIMG_15591920×1440 289 KB\nThe event started with Topcoder’s Community Manager, Jessie, and me kicking off the event and welcoming everyone. Later Jessie shared and awarded Topcoder’s regional award winners.It was followed by a session by @Aasawari and @Kushagra_Kesav. It began with an initial emphasis on the factors to consider while modeling your application and later they used Bookmyshow’s example to show how designing application schema is faster and easier with a code-first approach of data modeling with MongoDB.We also had a mini competition towards the end - where attendees were asked to design a MongoDB database schema for an e-commerce website. It was great to see the community interacting and learning in between the sessions and competitions. We are working on the results and will share the winners asap!We also had a quick workshop-styled session by Topcoder MVP @Sharathkumar_Anbu who spoke about changing trend data retrieval from RESTful API’s to GraphQL and backed that with a demo of how GraphQL query language gives developers a single API endpoint to access exactly the data they need. The code repo from the demo is available hereAlso for further reading on GraphQL do check out @SourabhBagrecha’s blog that can help you create your own Expense Manager App using MongoDB Atlas GraphQL API.\nWhatsApp Image 2022-08-05 at 3.57.21 PM (1)1600×1200 223 KB\n\nThe event ended with Pizzas , conversations, and a great event photo! (MUG Delhi-NCR is a clear winner when it comes to group photos )It was great seeing some of the regular and first-time MUG Event Attendees in @005_Atharva_Rustagi, @Harsimran_Singh, @Krishan_Singh, @Dhruv_Dewan, @33_ANSHDEEP_Singh @_avtej_ingh, @35_Manjari_N_A, @Rashi_arora, @Avneet_Kaur @DIVYANSH_KUMAR, @Samriddhi_Singh, @Samriddhi_Chandel, @Daksh_Makhija,\n@Rupin_Vijan and @Aviral_N_A come to the MongoDB office and attend the event. Always great to see you all! (I am definitely missing a few of you, I know).Big thanks to Topcoder and MongoDB Teams especially Shashank, Kalindi and Daniela , @Aasawari @Kushagra_Kesav and @Sonali_Mamgain who made the event possible. Not to forget big thanks to the workplace team and support staff who helped put together a great hybrid event.Hope you all had a great time and we hope to see you soon!–\nMongoDB Community Team",

"text": "Hello all ,Thanks for coming to the event and thanks Topcoder for collaborating with us.We have our results for the schema challenge we ran at the event. We thank everyone who competed and submitted their entries. In the final analysis, we found two submissions that were fairly close to what we expected. Congratulations to @_avtej_ingh’s and @Jugraj_Singh’s team for having the closest solution to what we expected.We really liked how @33_ANSHDEEP_Singh and @DIVYANSH_KUMAR approached the problem as well.According to the discussion during the session, data modeling with MongoDB offers greater flexibility and use case specificity. With this flexibility, you can select the data model that best suits your application and its performance requirements. In short “data accessed together to be stored together”.Generally, designing a schema or modeling your data depends on your app and its features and this becomes much easier when we are modeling for a non-relational database. We have prepared a solution for you to reference for a generic e-commerce app that has a product listing, a product category page, a cart, and an order portal.\nimage5560×4949 1.38 MB\nIf you are interested in Schema Designing and Data Modelling, check out our free MongoDB University Course on Data Modelling.Feel free to reach out to us and share if you need any help or have doubts while modeling your data.Best Regards,",

Do not disable swap in this case.Is it absolute? why?

For example, if you are confident in your systems workload & memory usage and know for certain that swapping isn’t required, then swapping could possibly be disabled in this case.One of the reasons that swapping is enabled is to help prevent the linux OOM killer from terminating the mongod instance. Perhaps you may wish to disable it if the OS the mongod instances are running on do not have a OOM kill function.I’m not too familiar with Docker but I hope these details help.Regards,\nJason",

The problem comes from the fact that there are lots of Sources ( e.g. GSMApi, OpenFigi) and lots of security fields on each of the sources. I am trying to narrow this down, but cannot seem to find a proper query to do so. Also I’m not exactly good with queries on MongoDB and anything I’ve tried so far is either 0 results fetched or an error. I believe these are not arrays, but rather nested documents. I have included current data structure in a screenshot. Also below fetches single result by using full path -db.getCollection(‘security-data’).find({“SourceFields.RemotePlus.Instrument_Issue_Issuer_Name.Source”: ‘Manual’})However RemotePlus.Instrument_Issue_Issuer_Name is not a constant, the manual update can happen anywhere, on any source and any of its field (even multiple) this is where I’m stuck.below is current data structure -\nimage1685×562 43.3 KB\nThanks!",

"text": "Thanks @Ed_Motor,I’m not too sure what you’re expecting as an output but I have done some testing to obtain the below output. From the sample document you provided, I can see there are 5 instances where \"SourceFields.<variable1>.<variable2>.Soruce\" have a value of “Manual”. Is that correct? If so, here is the output from my testing:The groupFilteredArray field contains 3 documents inside. However, it has 5 instances where \"SourceFields.<variable1>.<variable2>.Soruce\" have a value of “Manual”. From what I had counted from the original sample document, these were the paths where each instance existed:Note: The above output does not include the Original Source name / details (i.e. OpenFigi, ABCD, RemotePlus)I have assumed that there is 2 layers of “variables” for each of the input documents.Would the example output based off my testing include enough information to demonstrate all records (or “securities”), where “SourceFields.< *source* >.< *field_name* >.Source”: ‘Manual’ for your use case?I will also add, the way this is done is extremely process heavy. If possible, it may be best to retrieve the original documents and then filter them out from the application side. This operation i’ve performed may suit your use case if performed on a minimal set of document(s) (depending on your infrastructure / environment as well) in which you may not encounter resource pressure or long operation times. If you plan to run this as a “once in a while” situation, then it may work too assuming you are okay with the resource overhead.Have you considered re-designing the schema as I noticed there is more \"Source\" fields that have \"Manual\" as the value deeper in the same document (4th, 5th layers, etc.) and especially if you plan to run this filtering very frequently.Example aggregation for the above output:Some of the aggregation stages / operators used in the above for you reference:Very important to note I have only tested this a couple of times and on the single sample document provided. Perhaps other community members may be able to chime in with more suitable alternatives to the above example. I have used $project eventually in my testing due to the resulting document after each stage becoming too large to work with visually. You can adjust accordingly if you feel this works for your use case(s). It is highly recommend to test on a test environment to verify it suits all your use case(s) and requirements before trying in production. However, I would recommend going over the following documentation regarding schema design:Regards,\nJason",

"text": "@Jason_Tran thank you for reply/output provided!What you have provided I believe is good enough for me, because as long as I get:ObjectId(\"63116f45413bc94d7e966242\")I can then use these ids and fetch securities in question using API calls. It’s also very good that I can immediately view fields with “Manual”, even though I don’t see the top level, that’s not an issue at all.The 5 instances is exactly how many I would expect to be in the output in this case.As for process heavy I think it should be fine. Environment is spinning on AWS and there are plenty of resources and really this is more of a unique situation where I suspect some data may be causing time-outs, because it was manually amended and it is affecting only particular set of securities and only staging environment. So indeed it will be “once in a while” situation.In regards to re-design I can bring this up with developers as I’m more on end-to-end testing side of things. Interestingly I did try your provided query on my local instance with 6 sample documents and one of them having this “Manual” source, but got Fetched 0 record(s) in 0ms - is there anything I need to adjust in the query or it can be run as is?Regards,\nEd",

All you needed to do was run sudo systemctl start mongod (there are ways to get around using sudo to start a process, but every time I type sudo it makes me think about what I’m doing and why I’m needing elevated privileges) to get the service up and running.Then use sudo mongod command.There are limited cases where you should run a service using sudo, and mongod is not one of them. Running with sudo introduces potential security risks.As for creating /data/db, that is where MongoDB put the data files when it was first created and for several versions afterwards, but I believe the new location on Ubuntu is something like /var/lib/mongo which is more in line with standards and best practices.",

"text": "Hi @Rabindra_Acharya and welcome in the MongoDB Community !I might be wrong here, but it looks like you are trying to build something stateful in a stateless serverless environment.The MongoDB driver - Motor here - usually keeps a pool of connection open and these connections are reused. But if this pool isn’t persisted between calls and a new pool is recreated each time because the serverless environment you are using is stateless, then this just doesn’t work (and won’t).MongoDB Realm keeps a connection pool open and the same connection are reused between each calls.Here is an example of a REST API doing a findOne operation:As you can see, the connection to the Atlas service is retrieved from the context and from there, we can use any MongoDB query we want without recreating a new connection pool.Cheers,\nMaxime.",

"text": "@Thomas_Morten it is not clear what you are trying to accomplish. It seems like you are building a project that links directly to both zlib and libmongoc. You state that you want to compile the C driver static libraries, so I am assuming that you want to statically link libmongoc, but you do not say whether you are linking zlib statically or dynamically. I am going to assume that you want to want to link both statically.In that case, the correct way is to specify -DENABLE_ZLIB=SYSTEM. Then, if your system zlib is not in a location that can be located by the C driver build, you can also specify -DZLIB_ROOT=path/to/zlib/latest. Note that the ZLIB_ROOT should be the path that contains the lib and include directories created by the zlib build. On a typical system installation this would be either /usr or /usr/local. Most likely, you want to use whatever directory was specified with the --prefix option of the zlib build. The ZLIB_LIBRARY variable has no effect, so you can safely remove that.Your own project that then consumes both the C driver and zlib directly will need to build using the C driver static libraries and the same zlib static library. This will ensure that there are no conflicts between library implementation expected by the C driver static libraries and your own project’s static libraries.Either way, specifying -DENABLE_ZLIB=OFF is going render all the other zlib-related options useless, as the build will not include any zlib references. That approach is unlikely to be what you want, unless what you want is a C driver without zlib support.All that said, if you want static linkage of everything and if your own project uses CMake, then the easiest thing is going to be to make the C driver sources a sub-directory of your own build, include the C driver with something like add_subdirectory(mongo-c-driver), then link the C driver library to whichever of your project components need it with target_link_libraries(foo mongo::mongoc_static).",

"code": "majoritylocallocalmajoritymajority{w:0}local",
"text": "I’m posting in order to get some feedback on a general approach to selecting read/write concerns, in particular when isolated script executions don’t know they’re part of a wider “session”.I’ve been working for years with MongoDB, but have always had a hard time with read/write concerns. In particular how to set the appropriate concerns when the different parts of my application don’t necessarily know the full context of what has recently happened. The concept of a consistent session is easy enough to model in a single script execution, but introduce (for example) stateless API calls in quick succession and the concept of a “session” starts to span operations that are actually related, but have no knowledge of each other.Perhaps the safe thing to do would be to read and write majority for all operations, but some of my operations insert many thousands of documents and I want them done quickly. What I’ve ended up with is my application switching to unacknowledged writes when speed is required, then switching reads to local in case the next operation in the same script needs to read it back. It doesn’t really matter if unacknowledged writes get rolled back, but what does matter is that the next script execution has no context of the previous and so can’t choose the best read concern. To get around that I end up reading from the primary with local in most cases, which means no benefit from secondaries!I want to sort this mess out in a simple fashion, while ensuring that:One thing my application does know is how recently its state was modified. This is due to tracking all updates with a timestamp and incrementing number (in separate storage). So based on this I’m considering that my application could have two operating modes (Safe, and Fast) and switch between them based on recent activity.Safe: Write majority, Read majority from Secondary.\nUsed when there have been no recent updates and fast writes aren’t necessary.Fast: Write {w:0} Read local from Primary.\nUsed when write speed is required, or when there have been recent updates (which may still be running).What do you think? How have other people solved this problem? Feedback much appreciated.",

"code": "",
"text": "Hi @timw and welcome to the community!!If I understand correctly, you have an application that basically needs to do two things that appear to be in contradiction: one mode of working is fast writes, read the most recent data, don’t care if it’s get rolled back, and the other mode is consistency. Typically an application is one or the other (but you wanted both), so I’m not sure I fully understand the requirements. Could you perhaps post some scenario that the application handles that would help illustrate the day to day operation of the application?Also, to be more specific, could you please elaborate on a couple of points:It doesn’t really matter if unacknowledged writes get rolled back, but what does matter is that the next script execution has no context of the previous and so can’t choose the best read concern.This feels contradictory to me: since the writes are unacknowledged, there is no guarantee that the write even happened. Also what if the “next script execution” reads data that are rolled back? Is there a scenario that you can post so we can understand this better?This is due to tracking all updates with a timestamp and incrementing number (in separate storage).This follows the previous point: if the writes are unacknowledged and can be rolled back, why do you need to track these writes (that can disappear) on a separate storage?To cater for different application needs, MongoDB provides various combinations of read and write concerns settings depending on the level of consistency and availability required. However this requirement is typically consistent application-wide (i.e. consistency, or availability), so I might misunderstand your use case that appears to call for both requirements in a single application.Best Regards\nAasawari",

{
"code": "",
"text": "Thanks for the reply.The idea that an application has one set of read/write concerns for all operations makes perfect sense. I guess the short answer to my very broad question is “if you care about state at all then go for consistency across the board”. The presence of any unacknowledged writes anywhere in an application potentially breaks this model.I feel I’m trying to justify my requirements now, but I’ll try to clarify some points you highlighted…Re this contradiction: Some functions of my application can write tens of thousands of documents while many others can write a maximum of one. Choosing speed in all cases would increase risk in my application for the many operations that don’t need it. Choosing consistency in all cases would make the largest operations much slower. If I could choose only one approach I would choose consistency, but selecting the right trade-off for the right situation seemed desirable (when I built the system 10 years ago!). It didn’t seem strange to me that I’d want to benefit from MongoDB’s write speed in select contexts, but maintain a stateful application in general.When I say that failures “don’t matter”. I mean that they are very rare and any inconsistencies created by rollbacks are corrected soon afterwards. Hence accepting some risk in exchange for a lot of speed seemed reasonable, but only when necessary. I didn’t mean to say that I care about consistency sometimes, but not at other times. All operations are equal in this regard, but very occasional failure is tolerable.I track updates mainly for the purpose of cache invalidation. Clients requesting unmodified data will get 304 responses (and this saves me a lot of juice). I figured the same mechanism could be used to put the application into a secondary read mode. The worst case here (in the event of failed writes) would be the client getting a 200 response with discarded data from the primary. This is actually the default mode of the current system, so I thought a safe incremental improvement.I don’t mean to answer my own question, rather I’m curious if others have been through the same though process of choosing between consistency and speed at different times, and how they managed the potential consistency problems this creates.",

If you could provide static values for the \"_id\", \"investor._id\", and amount in relations to the sample document you provided initially that would help greatly.Lastly, please advise if you’re receiving any errors or unexpected behaviour regarding the investor field update. E.g. is the \"moneyReceived\" field within the \"investor\" array objects not being created or being created with the incorrect value or even in the incorrect object within the array etc.One thing I also noted in the above code is that the \"investor._id\" in the query section of the findOneAndUpdate() refers to an ObjectId() value where as the sample document provided has the value in these fields as string.

"text": "Hi @Vardan_Sargsyan92,The DiscardLocalResetHandler strategy discards the local changes and gets a fresh copy of the realm stored on the sync server. A destructive schema change makes this impossible as downloading the fresh realm is impossible given the mismatching schemas. In that case, your client and server need to re-align with the schema first, then sync can be restarted.I do destructive change and I receive the HandleBeforeResetCallback but I never receive the HandleAfterResetCallback even If I do not close the app for a long period of time. Besides, when I close the app and reopen it again I receive the HandleBeforeResetCallback againGenerally, when the DiscardLocalResetHandler strategy fails because of an error, it fallsback to the ManualResetFallback. So it’s normal that you don’t see the OnAfterReset being triggered. However, you’d see the ManualResetFallback triggered.And eventually, when I close the app and open it for the third time I get the app with proper sync.This is a little strange. Are you sure that in the meanwhile you haven’t updated the schema on the client to match the server?As a little conclusion, DiscardLocalResetHandler is expected to be really useful in a situation where the client and the server don’t share anymore the same history; but still share the same schema.It’s generally really helpful to have an overview of what could cause a client reset. I’d recommend to take a look at our docs about this subject.Additionally, we specifically explain in our docs that a destructive schema change is not something that DiscardLocalResetHandler can handle, and it’ll fallback to ManualResetFallback.",

Then both linked objects would need the ownerId field, but the link would be preserved.Otherwise, you’d probably want to look for common data patterns to sync on.

"text": "Here is some better documentation from another SDK (I’ve found some SDK flavors have more detailed documentation on specific topics).In the “to-many” section example:Again, this is the object model in the SDK, and your SDK syntax will be a bit different, but you want essentially to use this object model example and translate it to yours.Regardless of the SDK you use this with, here is the experience you will get:\nEach person instance will be in its own collection.\nEach dog instance will be in its own collection.personInstance.dogs will be an array of RealmObjects\npersonInstance.dogs[n] will be an actual, fully fleshed out data object. You don’t have to manually query them to resolve them from object ids. Also, each realmobject will have an id value in case you want the object id.You can do things like:\npersonInstance.dogs[n].name = “new doggie name”\nAnd this will persist back to the instance of the dog in the dogs collection. The person instance in the person collection just contains a reference (that is resolved automatically for you) to the instance in the dog collection.Also, with flexible sync, you don’t need to pull every person or dog in the collections for this to work. If you use a subscription, you can pass a query/filter/where syntax to pull down just the Person instances (and dogs as applicable) that are relevant. This is what Dachary was referencing:In this example from the swift-ui-tutorial link above, in your case, “user_groups” is Person and “user_items” is dogs. You need a subscription to each collection, and can filter down to some more limited dataset as appropriate. “ownerId” would have been set up as a “queryable” field.Make sure you have set permissions properly on the server’s collection permissions and not just filtering in the end client interface.Again, check out some subscription articles from various SDKs to get a more complete understanding of how subscriptions are handled.I was able to track down this documentation, so I think this is more helpful than my implementation as it will allow you to discover more answers to questions around these topics.

The swift-example you are refering to uses$0.ownerId == user.idSo here, we have a field called ownerId which is an ObjectId and not an Object. That means, this QuickStart does also not use real objects. For a field to be queryable, it cannot be a link if I understood correctly. So to your example to work, dog needs to be extended:And this is where my problem starts. I don’t want to model all references by objectId just because I need to query them.

Therefore, I can use the object id and work with it in permission rules and subscriptions without inconvenience. In the infrequent cases where I need the actual user data (such as in Account), then I’m just querying for the specific user.

In this case, ownerId is just a piece of metadata that allows you to sync the objects you want.

In this way, the separate view only appears to have one level of object, and things work.In my case, I have a parent object with a nested embedded object containing optional data.

You can go through the M220JS course to get more understanding about implementing the application’s communication with MongoDB using Node.js driver.Having said that I’d like to add a little into the discussion. The general advice is actually to have a pool of established, ready-to-use connections during the life of the application instead of connecting & disconnecting on every operation. All official drivers do this by default. Please refer to Connection Pool Overview for more details.With regard to your question:Second, never closing the database connection, will this cause a problemNo it won’t cause problems as long as the hardware is sized correctly for the workload. Official drivers manage the connections automatically for you to ensure this is as trouble-free as possible.

I would doubt that you’re planning on sitting on a computer accessing the “server” (Realm console) to input data - you may, but that’s highly inefficient.You’re overall setup will also be be different between partition and flex sync. With partition, you could have all of the items that are read-only on one partition that everyone has access to, and then each user could have their own partition. The downside there is that while the user sync’s to their partition which could be a small amount of data, the read-only partition dataset could be massive - or maybe not. So then you consider flex syncWithout knowing a lot more info, it’s going to be hard to make a suggestion, other than think through those use cases and write some code to see what works.",

Even if there was a crystal ball showing both would fit your data situation equally well, from a skills perspective I think it makes sense to go with Flex sync. More likely to continued to be used in the future with the current product or others, and then you don’t have a possible deprecation situation later on. Also cross training/documentation will live longer.Anyway, enough hypothetical… sounds like flex sync is the way to go for your situation with a “ownerId” queryable field on your documents that you apply permissions to.For all the ‘system’ documents, have the owner id set to a specific value and limit who can modify based off that. You can still give read access to everyone.For user documents, set the ownerId to the given user and limit permission based on that.",

In each project you’d then have a different cluster (you might use a much smaller cluster for dev, and maybe you frequently pause your test cluster, etc).Projects offer security/authorization level isolation (e.g. which team members have access) as well as isolation of configurations like Alerts which make them ideal for separating Prod from non-prod environments. A common pattern is to restore a backup from prod to a non-prod environment for test purposes. https://docs.atlas.mongodb.com/best-practices/#the-project-level may be of use.Taking a step back, I love the question because it’s good for thought for us to figure out how to make it easier for users to set up best practices.Cheers\n-Andrew",
