"text": "Hi, @ali_yeganeh,Welcome to the MongoDB Community Forums. I understand that you have some questions about implementing soft deletes with MongoDB.You could implement soft deletes via a data layer abstraction. You could expose an IRepository<T> implementation in your data layer that returns an IQueryable<T> to your application. Rather than returning coll.AsQueryable(), you would return coll.AsQueryable().Where(x => x.Deleted == false).If you are running on MongoDB Atlas, another way to implement soft deletes would be to leverage Atlas App Services. You could implement the soft delete logic using query filters:Regarding your second requirement of implementing a modificationDate, that would be easiest to implement in your application logic whereby you would modify a ModificationDate property on your base entity when the entity is modified. This could be done manually in every property or using an INotifyPropertyChanged implementation. Other options include implementing it in your Repository<T> implementation on update/delete. Yet another would be using Atlas App Services rule to set the modificationDate when updating or (soft) deleting an entity.Hopefully this provides you with some ideas for how to accomplish your design goals.Sincerely,\nJames",

See python - PyMongo cursor batch_size - Stack Overflow for an example of how this is done in Pymongo.Having said that, are there any specific reason why you want to manually set batchSize?

If you’re not mandated to use the Javascript function, is it possible to translate the function into aggregation operators instead?Lastly, $function was introduced in MongoDB v4.4 and I believe this is the functionality you’re looking for. However this would require you to upgrade to MongoDB 4.4, so this may or may not work for you.Note:\nExecuting JavaScript inside an aggregation expression may decrease performance.

"text": "I understand those are your requirements. The alternate I have suggested runs in both in Atlas and non-Atlas deployments of MongoDB. To be more specific, i’m curious to what the 3 conditions equate to as a goal - I.e. Do those 3 requirements equate to documents that have an invalid expiry date from your application’s perspective?In saying so, there a few ways that should be able to get the document(s) you’re after although i’m not sure if you’re wanting to use $search ONLY, whether additional stages are allowed, etc.For example, if you’re only wanting to use the $search stage and nothing else, you may be able to get these documents using the below example:The oddity here is that i’ve used a range of less than 1 to try and retrieve null values on \"expiryDate\". However, i’d recommend also voting for the following feedback related to indexing null data types. The mongosh output for testing if null is greater than 1:Similar to the above example I provided earlier, you can also obtain the same document(s) using a $match stage equivalent to my .find() example:Output:You could also do a combination of a $search stage that gets the path if it exists or not followed by a $match stage for documents that have an \"expiryDate\" field value that is greater than the specified date or equal to null. Although there would be no index usage here for the $match stage that follows.Please note:Regards,\nJason",

"text": "Hi. I have a trigger on my atlas database that creates a few documents in a few collections when a new user registers. These collections are to be synced to the new user because they define the layouts of certain screens in a MAUI app.\nI found that the first screen would not have received that data when I do my first realm.all for these collections. This is hardly a surprise because the request for all docs is done as soon as I go to the first screen after registering and logging in, so I assume it is before the database has had time to populate the collections. To get over this, I have a simple loop with a 500ms delay in it that attempts to get the data 20 times. This works quite well but I’m not sure if it is a good strategy.\nI then stumbled across something in the React SDK usage examples that talks about syncing in the background by making use ofconst OpenRealmBehaviorConfiguration = {\ntype: “openImmediately”,\n};which is used in the Realm.open configuration. I then looked for this in the .net SDK but there is no mention of it. I tried to use it in my .Net MAUI app but it does not know about OpenRealmBehaviorConfigurationI have a few questions.\nIs it correct that this is not available in .Net and will it be available soon?\nIf I can’t use that, is there another way in .Net to achieve the same so I don’t need to perform a realm.all\nIf none of that is available, is my loop a good workaround or have I missed the proper way to solve this problem?I also have an unrelated question. Currently I have 1 realm per model (collection). Is that correct or should I have 1 realm for all my models / collections?

Please note that if you’re doing this too soon it could still be that the server didn’t have time to correctly process the documents you just added with the trigger.Regarding the other question, usually it’s an overkill to have one realm per model. How many realms you need and what models you want to sync in each of them really depends on the structure of your data, of the application and how you want to manage all of it. That said, you can also just have one realm for all your models if that works for you.I hope this helps ",

The more I learn, the more I realise I don’t know!I was already using realm = await Realm.GetInstanceAsync(syncConfig); and have addedawait realm.SyncSession.WaitForDownloadAsync();but that returns immediately. Presumably, it s too soon for the trigger and function to have started to create collections. This means I need to stick with my loop or find an alternative. I have 5 small docs in the collection in Atlas, and on one occasion, I had only received 2 docs, so my loop exited before the other 3 had been received. I tried dropping my delay from 500ms to 100 ms expecting to receive part of the collection much more often, but weirdly, I keep receiving all 5 now. I expect this is always a possibility.However, I noticed something else, which almost certainly means I need to change my strategy. After receiving the 5 docs and showing them in my UI, I then added a new doc in Atlas and expected to see it be added to the UI automatically. The reason I expected that was because if I change a doc in Atlas, the UI does update to show that in my app. I expect this is because the realm contains records that I update but does not contain docs that I add in Atlas. I did expect sync to cope with that.Can you please confirm that to handle adding docs in Atlas (or on another device), I need to subscribe to changes using a realm change listener and when that event fires, I need to do a realm.All?After your previous reply, I think I understand more about realms (I’ve done some more reading as well).

If the objects have been added locally or in Atlas the listener should fire anyways. It could be that the objects that you’re adding to Atlas don’t follow the schema you’ve defined, and so they do not get synced back to the application or maybe they are not in the set of the results for the subscription queries you’ve defined (I suppose you are using flexible sync, am I correct?).",

I may be able to make a simple app that shows the same problem.I don’t want to get into subscribing tp events unless I really need to. I thought I read that is only necessary for background threads. This is simple UI updating that I’m hoping normal sync looks after. If I really need to subscribe to events, then I’ll create a cut-down app that you can look at.The object added in Atlas definitely follows the schema because all I did was clone a document and change a few fields in it. When I force a realm.all in the MAUI app, then I do receive the new record. The only query I have defined is a realm.all so it should receive any inserted records at Atlas. The UI definitely updates automatically if I change fields in a doc in Atlas.I am making use of MAUI data binding and that is working perfectly for updates. I’ll tidy up some code and paste some snippets here soon.You seem to have confirmed that insertions at Atlas should automatically be added to the MAUI UI, so that is good to know. When you say“maybe they are not in the set of the results for the queries you’ve defined”perhaps I have not defined the query properly such that Realm knows about it?

I’ve corrected the text in my previous post to make it clearer, but you can disregard it in your case as you’re using partition sync.Regarding the UI not updating… I can see what’s the problem here. You are wrapping the realm collection in an ObservableCollection, but this way the realm collection doesn’t fire all the notifications that the UI binding framework uses to update the UI.\nYou should simply do: Reminders = realm.All<>().OrderBy(....). Realm collections are live and implement INotifyCollectionChanged that is used by MAUI to update the UI accordingly. As a general rule you should always try to use Realm collections “as they are”, without wrapping them in other things, as you could lose some of the advantages of live collections. That’s also the reason why you should also avoid using ToList(), as the collections that you obtain is not live anymore.\nAs an additional note, the reason why updates to single fields still works is that even though your collection is not live anymore, the single objects that are part of the collections are still Realm Objects, and as such they are still live and implement INotifyPropertyChanged and so the UI can change when their content changes.I’ve seen that in another thread my colleague already recommended an article that I wrote about How to Use Realm Effectively in a Xamarin.Forms App. Maybe that’s a little bit long for an article, but if you want to see some simple code you can take a look at the example we have in our repo, QuickJournal.

"text": "Hi @Rayyan_Khan,In a standalone deployment (generally for development) or a replica set deployment (minimum recommended for production environments) each mongod process stores the same data.If your use case merits a larger or more distributed deployment, sharded clusters allow you to define a per-collection shard key index to distribute data. Sharded clusters have additional infrastructure components including config servers which keep track of the sharded cluster metadata and mongos processes which route queries to the correct member(s) of the sharded cluster based on the query and collection’s sharding metadata.A database in a sharded cluster can have both unsharded and sharded collections. Unsharded collections live on primary shard for each database; data in sharded collections is partitioned across available shards based on a chosen shard key for the collection. For more information, please review mongos Routing and Results Process in the MongoDB documentation.From an application/driver point of view, you generally do not have to keep track of the cluster topology. The driver API includes discovery of changes in configuration and availability for replica sets and sharded clusters. However, you can specify read preferences if you want to route queries to specific members of a replica set and set up up zones for sharded clusters for more control over read and write distribution of sharded data.If you would like a more detailed introduction to MongoDB deployments and configuration, there are free online courses for DBAs at MongoDB University including M103: Basic Cluster Administration.Regards,\nStennie",

You can also try adding 0.0.0.0/0 temporarily for troubleshooting purposes and see if you can connect after.If you believe this is already done, please try performing the initial basic network connectivity tests and provide the output for the cluster you are having trouble connecting to:Note: You can find the hostname in the metrics page of your clusterAdditionally, I would recommend to review the Troubleshoot Connection Issues documentation and verify some configurations, such as adding the client’s IP (or IP ranges) to the Network Access List.

For example, if your dump was created from a MongoDB Server running version 4.4.x , be sure that the MongoDB Server you are restoring to is also running version 4.4.x .In addition, ensure that you are using the same version of mongorestore to load the data files as the version of mongodump that you used to create them. For example, if you used mongodump version 100.5.4 to create the dump, use mongorestore version 100.5.4 to restore it.In short specific to this scenario you’ve described; restore to the same MongoDB version and then upgrade to 6.0. See the documentation for more information regarding the Upgrade of a standalone to 6.0 (You can find the associated Replica Set and Sharded Cluster upgrade procedures and notes on the left hand side of the linked documentation).Hope this helps.Regards,\nJason",

When importing the AWS SDK package, it would take anywhere from 3-15 seconds for the function to return. Nearly all of this time was spent on the module being loaded which I tested by removing all of the signing function.Now having moved the same signing function to use the 3rd Party Service, the function consistently returns in hundreds of milliseconds or less.If the import of AWS-SDK speed is not fixes, and the AWS 3rd Party Service is discontinued, I will have to move away from realm functions because the speed is too unreliable.",

To match the firewall settings of your mLab Sandbox or Shared plan deployment you can whitelist all IP addresses (0.0.0.0/0) on your Atlas cluster.…so it appears that even with a cheap(ish) shared plan there is no way around the whitelisting all IPs issue.…but, then there is this:However, we recommend whitelisting only the addresses that require access. To match the firewall settings of your mLab Dedicated plan deployment on Atlas you can review your current mLab firewall settings on the “Networking” tab in mLab’s UI.…and:If you’re connecting to MongoDB Atlas from a Heroku app, it’s most likely that you need to whitelist 0.0.0.0/0 (the range of all IP addresses) unless your app is in Heroku Private Spaces. Heroku IP addresses are, in general, highly dynamic. As such most mLab and Atlas-hosted deployments used by Heroku apps allow all IP addresses.…and from this link:Heroku Common Runtime Dynos use a subset of the IP range of the underlying AWS EC2 instances.The underlying AWS region for your app can be found as the provider.region field in the output of this CLI command:…and also from the same link directly above:The IPs in use by Heroku at any given time are highly dynamic, meaning that the published ranges may cover other IP addresses not currently in use by Heroku. This means that it is often not desirable to open up your firewall to the whole of the AWS region for security reasons.…and lastly:For apps in the Common Runtime a better approach would be to use an add-on to provide a static outbound IP address Add-ons - Heroku Elements or to rely on secure communication via TLS.I’m going to have to read up a bit more and look into the network service add-ons listed that Heroku provides to see if I can find a solution. I did try using Fixie Socks for one of my own sandbox applications, but that didn’t seem to resolve the issue:-)Cheers:-)Juliette",

In short, there’s typically no need to change this value unless your needs is very, very specific, and also after a deep troubleshooting by a MongoDB engineer.It’s generally more beneficial to increase the amount of RAM in the machine, instead of changing the WiredTiger cache size.Having said that, what issue are you seeing? Are you seeing slow queries, extremely busy disk, or similar performance issues?Best regards\nKevin",

"text": "Hi @satvant_sandhuI’m afraid analysing WiredTiger performance and other deep performance-related issues is not as simple as checking some statistics. The reason why MongoDB records thousands of statistics each second in full-time diagnostic data capture is because all of them have to be examined holistically in relation to one another. There is no single metric that can tell you what’s happening in the system. Note that these metrics are just one of the important tools to troubleshoot a deployment, but it’s not the only tool. In a typical investigation, FTDC data, disk data, OS data, and all relevant information are collected and examined thoroughly, so doing that on a public forum is extra challenging Having said that, we can sort of see if a deployment is overworked by checking some things:Ideally you don’t want to see high dirty in mongostat (high used is ok – and healthy, and you want this to be about 80% – but this also depends on the use case), low delay in IO operation, and no slow queries in the logs.Best regards\nKevin",

For the most cases, a collection is much more often being read than written. That means, that having denormalized data model will provide good benefits, even though, you will have to write more code to take care of the data consistency across collections. So, usually, it is worth it To get the number of reads/writes - execute this in the shell:It will output this object (I removed and reordered some props for simplicity):Roughly:\nNumber of reads = search calls.\nNumber of writes = insert+modify+update+remove calls.also the People collection is use on everywhere on my mongo, , if user want to update, I should update many collections ?Let’s assume, your have 3 collections:Notice, that documents from ‘players’ collection are used in ‘teams’ and in ‘coaches’ collections.\n‘coaches’ collection uses normalized model (only _id as reference to document from other collection is used);\n‘teams’ collection uses de-normalized model (beside immutable _id there is also player’s name included);The benefit of having ‘name’ prop beside ‘_id’ in ‘teams’ collection is that you may not need to join players to teams to get player names, which will improve performance. But you will need to make sure that all collections would have same value for player’s name.Now, a bit about consistency maintenance:But, it worth to day, that with MongoDB, you will have to manually take care of the data consistency, if you have 100% normalized data. For example, if you delete any player from ‘players’ collection, you will have to update 3 collections, because they use a bit or more of player’s data!any option beside on your options above ??Yes, you can take the free course on the MongoDB’s aggregation framework and try to extend and optimize your pipeline.",

Projects contain tasks, and those tasks contain subtasks, and each of them has user activity so if one user checks one subtask, then the other user should be able to see that subtask as completed in real-time. This can occur at every level, including the project, the task, and the subtask. It is also possible at each level to have a full notes section that would function similarly to comments, allowing each user to leave a comment and receive a response.",

"text": "I have an MVVM MAUI app that is working fine when running in Visual Studio in debug mode. If I build for release and deploy and run, it crashes when a change in the UI causes MVVM to tell sync to send back a change. The error is “Cannot modify managed objects outside of a write transaction.”. I know what that message means but here it is when Realm code is being notified of a data change in the UI via MVVM so it is not my own code that is changing data without a transaction.To test this theory, I ran the “House Moving Assistant” sample app as demo’ed by @Luce_Carter at the .Net MAUI conference and it has the same problem when I build it for release. Again it works fine when running in Visual Studio in debug mode. In this sample app, I can add tasks but when I tap one to update its status the app crashes and log cat shows the above error. I’ll include part of the log below.I see the same on a Samsung phone (Android 12) and a Samsung tablet (Android 11).John.",

"text": "The MongoDB Node.js team is pleased to announce version 4.9.0 of the mongodb package!We have corrected an inconsistency with our writeConcern options in the type definitions where the MongoClient alleged to not support “writeConcern” as an option. In fact, it did support it at run time and now the types correctly reflect that, along with the corresponding deprecations we made to the nested writeConcern config settings.Our index specification handling had a few peculiar edge cases that we have detailed below, we believe these are unlikely to affect a vast majority of users as the type definitions would have likely reported an error with the impacted usage. As a feature, the typescript definitions now support a javascript Map as a valid input for an index specification.As per usual this release brings in the latest BSON release (v4.7.0) which added automatic UUID support. You can read more about that in the BSON release notes here!Special thanks to the folks who contributed to this release!We invite you to try the mongodb library immediately, and report any issues to the NODE project.",

"text": "It may seem not to be a pure MongoDB problem, sorry for that.I know that I can listen to onUpdate event and use editor.getJSON() to get changed content, then I can set this content through an API to the server. Then the server updates a field of MongoDB with the new value(I may store it as a JSON string).I have a few concerns about the above simple design choice:If the user only updates a small piece of document, I have to send full document JSON to the server and update the full content of the MongoDB field; all of these seem too costly.In the frontend, I may use a throttle to reduce trigger frequency, but I still have to send full JSON. It may be a bottleneck as content increases with more text and images.Can I only send the content change to the server like collaborative applications? But I have no requirement for collaborative editing between users. I only want to support fast client/server synchronization. Is Y.js a proper solution for me? If there are some better tools for me, please let me know.And if we could send the change of content, can we update the partial JSON string on MongoDB? The content of tiptap may be a complex nested JSON. Is it possible?",
