I now run two systems in parallel (one with MongoDB 4 and one with MongoDB 5) and these are my observations for a collection with lots of data:Other indexes also increase, maybe because of the increased space for the _id_ field. What can be the cause of the index growth? The only change in configuration I did was to seperate the database to an own directry (directoryperdb=true).Records are inserted to the collection with a rate of about 1000 docs/second and get removed by a TTL-index.Thanks for any hint\nFranzPS: The update was not a real update.

My client is a SpringBoot Application using the Spring Data MongoDB framework. The id is of the org.bson.types.ObjectId type. I do not set the id myself. This is done by MongoDB (or the Spring Framework). The ids look ‘normal’ like this (in both server versions):With the server update I also updated the client to use the java driver version 4.6.0 instead of 3.11.2. I have also observed a drop in performance here (in my use case). I cannot say whether this is connected to the larger index. It could also be due to connection pooling or something else. When I use the old driver version (also with the new MongoDB 5 version), I do not observe any performance loss. Therefore I think the problem is more on the client side.Thank you for your efforts\nFranz",

But as docs are added, removed, added, removed and updated, the entries start to spread and keep space in between.If you rebuild an index it will be very compact but also have no space in it, if you then add things to it that are spread through the index it can rapidly grow as it has to split every block to make room for new entries.So depending if the collection are freshly loaded or used for years, this can make a huge difference. It doesn’t mean that this makes the index less efficient though. Performance issue could be related to a bunch or other reasons.",

This will make the sizes consistent as written on disk. Without fsync, you might find that the sizes keeps fluctuating before it settles after a minute (WiredTiger does a checkpoint every minute).In addition to the _id index, I also created a secondary index just to double check.What I found is that secondary index sizes are quite consistent from 4.4 to 6.0, with 4.2 being the odd one out. With regard to _id, 4.4 to 6.0 are about 130% larger than 4.2.I believe what you’re seeing was caused by the new-ish (from MongoDB 5.0) WiredTiger feature of Snapshot History Retention. The introduction of this feature changes a lot of WiredTiger internals, and this is one of the side effect of the change. To be complete, this issue was known, and was mentioned in SERVER-47652, WT-6082, and WT-6251.Hope this explains what you’re seeing here Best regards\nKevin",

This token remains the same until it expires.\nEvery time I create a new site, I generate a new partition and push that partition to the writePartitions array of the user’s custom data collections, but the JWT token stored in localstorage of the client does not have this newly created partition in his writePartitions array.\nThis cause the subsequent http calls to transfer a wrong list of partition to the server that returns a wrong list of sites inside the watch() functions.I solved this adding a forced refresh of the access token before the find() call:after this, all became working like a charm.",

"text": "Hello, seeing how we plan to host our database on MongoDB it seemed a logical step for us to take from it as much as possible and thus we would like to embrace Atlas Search as the main workhorse powering our search heavy systems.I have tried playing with it for the past few days, and while I find the initial setup very easy to do, I have faced some problems/ questions.Considering the following document:And the following Atlas Search setup:\nimage1075×720 17.9 KB\nProblem number 1:Searching for this documented by address, entering Some Str, 20 will successfully find it, however as secondary findings it will also list unrelated documents, only because of the matching street number, for example:Completely Unrelated Str, 20\nUnrelated Square, 20\netc.Could you tell me please what I am doing wrong here, and how could I finetune this?Problem number 2:As you can see, there are more fields set up that I would like to search this collection by. However, for some reason I am only able to search the documents by the recipient.name and address. If I were to search by expirationDate, be it an exactly precise value, e.g. 2022-09-25T20:19:42.001Z or just 2022, I get 0 results found. The same happens if I attempt to search by shipment ID, for example “CXE-43556546”.It puzzles me, because as you can see, the fields are inserted into the index and I was not able to find the solution on my own to this problem online, therefore I would like to kindly ask you if you could tell me what I am doing wrong in this case.Problem number 3:Finally, I have noticed that Mongo product managers frequently visit these forums, so I would like to report a translation problem regarding the pricing page on your website.Since I need to present MongoDB Atlas to several people I opted for your webpage in Italian, and most of it is translated. However, the most important section, that is the plan comparison table, still appears in English, the currency is presented in dollars, feature comparisons and descriptions are written in English. It is a jarring experience having to present your product to my peers in such a half-localized fashion.Grateful,Ben",

Sample topic is: Scaling a data model using bloom filtersDoes this make sense or can you suggest something else? How can I use it if it makes sense?@steevej I am already using this.

It is a very structured data model. Fixed and stable.\nBecause you can run 2 extremely quick queries, by index, just subtracting the like/disliked profile ids by a given user from the currently online ids (from a given geo area). The online table (if geofenced and including recent activity) is relatively small, compared to the number of likes/dislikes.\nI ran some tests on postgres in a simple VM, and it worked well (but I didn’t create 100M records… true).That being said…\ncertainly there is a solution in mongodb, but using arrays will eventually hit a brickwall because they have performance limits when they go past the 10ths of thousands.\nIt is more likely just insert one document per like/dislike and recent activity, get all of those by index quickly, and let the code in the app sort out the needed and not needed.also, you just need to get some results, not all, to the user quickly. While the user selects, clicks or not on some profiles, you can get some more behind the scenes br,\nJP",

If you restarted the process, how did you do it?making bindip only to 0.0.0.0 works fine and I 'm able to access the db via remote host however worried if it has any security concernsSetting bindIp to 0.0.0.0 just means that mongod will listen on all network interfaces. If your host has a network interface that allows incoming traffic and you don’t have firewalls in place blocking public traffic to port 27017, then you have every right to be worried about security concerns. If your server has two network cards in it, one for external and one for internal traffic, then 0.0.0.0 will bind to both of these which is not good. External network traffic does not need to connect directly to your MongoDB servers.I would set my bindIp up to be 127.0.0.1,10.x.x.x. The 127.0.0.1 address is your localhost address so can connect locally from the machine without it going over the network. If you don’t want people to connect from the MongoDB host, you can leave this IP address out. The 10.x.x.x would ideally be an internal only interface that does not allow for outside your network traffic. I only recommend using 0.0.0.0 for testing purposes and then recommend changing back to more restrictive IPs.The configuration docs have a small section on security considerations.

Same thing happens when I tap to go to the detailView where the view increment happens onAppear and also when I go back to the listView. Even just scrolling through the list can be quite laggy.

So I can show a progressView while the collection is loading.So basically my problem here is that every transaction just freezes up the UI and I think should be moved to a background thread, but I am not sure how .

The only difference between Community & Enterprise editions is that the Enterprise edition allows you to use automatic encryption:Otherwise both editions are equally secure.If you can use Atlas, it provides encryption-at-rest by default, and you can also manage your own keys to do so.Best regards\nKevin",

You will want to filter out as many documents as you can early in the process so you’re sending the least amount of data through the pipeline as possible.Not knowing how your data is distributed, and how many elements are in each grades array, it’s hard to make any assumptions about performance. Add on top of that, the hardware and resources available also have impact on how the query will run. Another thing to take into account is how often to you expect this query to run? If it’s infrequent, then it could be a little slower and not cause much in the way of problem for day-to-day operations. However if it’s running frequently you will definitely want to make sure you get it as performant as possible.Here is another version that will do the same thing for you. This one filters out any documents that don’t have a grade of 90 or greater in the grades array and should be able to take advantage of an index on grades.grade.I haven’t take the time to build up a larger dataset for testing to see which might be better, but even if I did, that would just be with dummy data that may not even be close to what you have in reality. Take some time to play with both queries. Tweak as necessary. Look at the results of running an aggregate query with the explain option and look at the results to see you can get things to run optimally.Being new to a technology can be frustrating at times because there’s so much to learn and you don’t always know where to start, but at the same time you have the enjoyment of learning new things and the sense of accomplishment that brings when you figure something out.The documentation is a great place to learn. If you have yet come across it yet, MongoDB University offers free online courses and they have both admin geared courses and those that are geared to developers. And always feel free to stop by here to ask questions. The community is great and lots of people around helping out our fellow travelers on the path to MongoDB mastery.",

This looks like O(N), which is unreasonable. There should be a way to obtain that information as O(1) if the whole index count is requested, and at worst O(log(N)) in case counting the number of documents is operating on a sub-index.\nI am using the MongoDB C driver, so the solution I need must fit within the API provided by it.

The part that troubles me is “no action is needed, as the client has already established a new connection to the sync server to complete its upload”, which seems to indicate that this shouldn’t be an error.It’s also worth noting that before getting this specific error, users got another error for a few months, “Bad progress information (DOWNLOAD)”, which also prevented them from using the app.I’m guessing the source of the problem is a schema inconsistency, however this should be resolved by now. My concern is that such errors should be solved by doing a client reset, which is not the case here.How to get sync to work again for those users?",

"text": "Hello @Jean-Baptiste_BeauMy name is Josman and I am happy to assist you with this issue. Usually, a BADCHANGESET (DOWNLOAD) error is an error related to the history for a said partition. These types of errors can occur due to actions that are not permitted like making changes to schemas with development mode Off, setting incorrect partition value, syncing to/from incorrect partition, etc.In your particular scenario, it appears that the client is unable to rebuild the history for a particular partition due to two (or more) operations that are not congruent with each other, i.e. an update after a delete related to the same id of a document.Currently, there is only two possible solution to this error:Please let me know if you have any additional questions or concerns regarding the details above.Kind Regards,\nJosman",

"text": "Hi @Josman_Perez_Exposit,Thank you for your answer.Terminating Sync is a very risky and troublesome process, as you pointed out, and the last times I had to do it were absolute nightmares, causing the app in production to be down for a few days.Isn’t it possible to restart sync (or something similar) only for some users? I find it very surprising that to solve the problem of one user (or a few), I have to put the whole thing down for everyone.Thanks,\nJB",

The badchangeset problem you are experiencing for that partition is making the client not be able to restore the history for the same. If you could open a support case, we would be able to help you in the best way possible and investigate further if we could solve this without terminating Sync.Please let me know if you have any additional questions or concerns regarding the details above.Kind Regards,\nJosman",

It takes more than 2 mins during Realm async open to actually start downloading any data. Moreover, it isn’t the first launch. It takes 4-5 mins to async open Realm on app restart.So it takes 140 seconds to start the download and just 10 seconds to finish downloading. That’s beyond any expectations. Especially because all the data should already be available locally but it looks like it redownloading everything after the app restart.UPDATE: It looks like MongoDB was just updated from the 4.4.10 to the 4.4.11 and it works just fine after restart. Though, not sure if that’s a restart or version update that helped.UPDATE 2: This is happening again right now so it was not fixed . The strange thing it is happening 3rd day in a row at the same time. It took 8 minutes today to startup the app. The server load is just zero but it works like under 1000% load\n\nimage1280×222 64.3 KB\nUPDATE 3: It works fine on the AWS Ireland (eu-west-1) M0 machine but for all our AWS N.

"text": "Hello @NightNight , sorry for the long reply on this. Usually, it is a good practice to wait a minimum of 10 minutes before terminating and reenabling Sync to allow the Sync process to prune all pending operations.Note that the Realm database on the server is common for all your Realm applications within the same project. When you terminate a Realm application, the server process must delete all metadata associated with that application. So, although you can terminate and start it without any problem, depending on the size of the stored data, it is recommended (as a good practice) to wait a minimum amount of time to ensure that there will be no problems when restarting Atlas Device Sync again.Please let me know if you have any additional questions or concerns regarding the details above.Kind Regards,\nJosman",

This is resulting in the driver throwing an exception when attempting to process the message:As the change stream implementation is watching changes, we ideally do not want to miss any updates. We, therefore, use ResumeAfter with the ResumeToken._data field of the last successfully processed event. As the event cannot be deserialised by the driver, we can never get the bad messages resumption token to skip over it causing continuous failure.Are there any ways to get a change stream event resume token without loading the message?

"text": "Hi, @Anthony_Halliday,I understand that you’re having a problem with returned ChangeStreamDocument<T> objects exceeding 16MB. This is a limitation of change streams because the returned document is a BSON document itself and must fit within the 16MB BSON limit. This limit can be encountered more frequently when requesting pre-/post-images of the affected document in the change stream.Since the change stream document cannot be parsed, you cannot access its _id, which is the resume token. You can however call cursor.GetResumeToken() even after the change stream throws.Note that the resume token returned is probably the change stream event that exceeded 16 MB. Thus you would need some additional logic to skip over the offending change stream document, restart the change stream without pre-/post-images, or include a pipeline that performs a $project to omit fields and reduce the change stream event to less than 16 MB.Another potential solution would involve tracking the last successful change.ClusterTime - which is a BsonTimestamp - and using that with ChangeStreamOptions.StartAtOperationTime after incrementing the BsonTimestamp enough to avoid the >16MB change stream document. BsonTimestamp consists of an Increment (monotonically increasing counter of operations within a single second) and a Timestamp (seconds since Unix epoch).Hopefully that provides you with some ideas of how to work around this issue.Sincerely,\nJames",

You can use any of the MongoDB Backup Methods applicable to your deployment type and MongoDB server version.I suspect the inefficient backup approach was referring to mongodump and mongorestore. Per the Performance Consderations section of the documentation for Backup and Restore with MongoDB Tools:Because mongodump and mongorestore operate by interacting with a running mongod instance, they can impact the performance of your running database. Not only do the tools create traffic for a running database instance, they also force the database to read all data through memory. When MongoDB reads infrequently used data, it can evict more frequently accessed data, causing a deterioration in performance for the database’s regular workload.I was wondering what will be the “limit”There is no specific limit, but if your data is significantly larger than available memory there will be more overhead for reading data with a mongodump backup and more time to recreate your deployment with mongorestore. The timing and performance impact of backups will vary depending on your backup approach, deployment resources, workload, and backup frequency.The MongoDB server documentation includes considerations and procedures for supported backup methods.Regards,\nStennie",

That’s why I skipped the shard replica set creation: even without it, I observed the same behavior. When my config replica set is healthy, MongoS accepts connections. But when the config replica set is in degraded state and the remaining servers are rebooted, MongoS refuses connections until the config replica set becomes healthy again.Thanks for the toxiproxy recommendation, I’ll look into it. But I feel like turning off servers is also a valid test case: in case of datacenter emergencies, we may have to power off some servers quickly - and even in this state, I expect the remaining servers to still accept connections.",

"text": "Hi @martin_daniels ,To me it sounds like the outlier pattern with story documents is the way to go.The Outlier Pattern helps when there's exceptionally large records occasionally occurring in your data setThe idea is that you have each story as a document in the story collection, with its data and embedded array of users that viewed the post :When a specific post gets more than “N” number of distinct views (lets say ~200) we open a new document and paging those viewers. You can index {storyId : 1, \"users.userId\" : 1} to use it for a query to determine whether a user has already viewed that story or is it a new user…Now there will be a TTL index on the “storyCreateDate” and therefore all the documents will be deleted at the same cycle. Having said that the total views for a story will be calculated from a sum of views on each document or maintained in the “overFlowIndex : 1” document and incremented every update.Now to get all the documents of story xxx I need to query:If you need to sort the documents based on insert order:Now when indexing {\"storyId\" : 1, \"overFlowIndex\" : 1} you will get an indexed query to get all overflow documents.Regarding the trigger to delete the S3 files there are 2 solutions:Thanks\nPavel",

"text": "Hi @sai_sankalp and welcome to the community!!I believe it’s possible to achieve what you need by using the aggregation pipeline as the update operator using update_one, update_many, or find_one_and_update. This feature was added in MongoDB 4.2.Note that newValue is a list instead of a dictionary, which signifies that this is an aggregation pipeline instead of a simple update document.Please refer to the documentation for parameters of update query. which explains the same.As an example, using pymongo:\nThe query created a filter and the newValue basically contains the aggregation stage which sets the updated values.The output for the above query would look like:One suggestion I would like to make from the example you posted is that you might want to rethink the use of a string combined with date datatypes in your new_data and old_data fields. If these two fields are supposed to describe dates, I would recommend you to keep the date datatype, which will make it easier to manipulate in the future.Please let me know if you have any further questions.Best Regards\nAasawari",

For example, openpyxl is a Python library to read/write Excel 2010 xlsx/xlsm/xltx/xltm files. Excel files can include more complex content like formulas and references, so I recommend exporting to a text-based format like CSV if you want to transfer data between environments.That depends on the sort of data you are trying to export from Zoho Analytics and how (or if) you plan to automate any integration.General approaches might be:export from Zoho Analytics to CSVscript something to sync data using the Zoho Analytics APIask for suggestions in the Zoho Analytics CommunityRegards,\nStennie",
