  1. Self-Managed Computed Collections

    This feature would enable MongoDB to automatically generate common patterns by computing entire collections. A particularly useful application would be the ability to identify duplicate fields within a collection and create a computed collection that groups all possible duplicate together.

    Sometimes, a field is duplicated between two documents, while another field in the same document is duplicated across seven other documents. Each of these seven documents might have fields that are duplicated in yet other documents, leading to a vast iteration in search of possibilities.

    Having MongoDB abstract all this logic in a performant manner to create computed collections would…

  2. How to limit the number of document updates?

    Hi
    I want to limit the number of document updates in one command.

    for example

    db.users.updateMany(
    <filter>,
    <update>,
    {
    limit : 100
    }
    );

  3. Make account connections stable

    My account is stuck in "We are deploying your changes (current action: configuring MongoDB)" endless loop for the entire eveing and I cannot finish my project for tomorrow. Cannot connect to my database even with a saved IP.
    Yes it's a free account, but this is not a way to just kill any possibility to connect to a simple database. This is a flop

  4. Improve Changestream metadata by including userId(who), action/intent (event name).

    This can be done by including meta data in the options for C(R)UD operations!
    Something like: User.updateOne({ _id }, { $set: { name: "newName" } }, { $meta: { userId: _id, action: "nameUpdated" })

    This is super useful because now changestream can be used to create event store or audit logs, out of the box. I just have to store all the changestream events from the relevant collections. This also makes event driven architecture in micro services super useful. Developers can use this to publish events directly to a message broker such as kafka, where action would be equivalent to…

  5. Fine-tune the update privilege action

    We want our devs to be able to update docs, but only one at a time. If they need to update a bunch together, they should check in with the DBA. Right now, we can't fine-tune the update permissions like we'd prefer, so we're looking into ways to make that happen. This will help us manage document updates better and add a layer of security.

  9. Unique Indexes and Bulk Upserts for Time Series Collections

    We would like to insert data in bulk into time series collections and identify the new data that has been inserted without the possibility of duplicates being inserted.

    For regular collections this is achievable by adding a unique index and performing a bulk upsert (as any duplicates will be rejected due to the unique index).

    For time series collections however unique indexes are not currently supported.

    In addition performing an upsert with $setOnInsert option which should only action insert operations is also not currently supported for time series collections.

    At the moment the only options appear to be:

  12. AWS IAM Role integration with MongoDB On premise

    We are planning to integrate AWS IAM Roles/Users with MongoDB On-premise for password-less authentication. So the authentication happens through IAM Profile. However, we noticed currently MongoDB on-premise doesn't support AWS IAM Role integration. This is a blocker. We want the authentication would happen through AWS IAM Profile rather than Standard Credentials.
    This would eliminate or significantly reduce the use of Database Credentials while tightly integrating with AWS Services. Simultaneously, applications can securely connect to MongoDB via AWS Profile.

  13. array length as computed to be indexed

    in some cases, I need to filter only docs with specific (or range of) sizes of nested arrays.
    it will be good if I can configure 'automatic index' to keep the length of the array, based on the field name I will provide to the index, and then I can easily get the docs.

    (now I need to add and maintain this field on myself or with trigger)

  14. Collection which stores last login date_time for the users

    Are you please able to store the last login date_time for the users which exist either in admin database or $external database in a collection of admin database of that cluster or opsmanager database which manages the clusters?

    I have a requirement at my end - is to find the users who havent logged in for 60 days, , their roles to be revoked. And, ultimately delete the users who dont have any roles attached after a fixed period of time.

    I do undertsnad you store the login details in audit logs. But that would be a tedious process at…

  16. Allow disabling auto removal for capped collections

    Capped collections work as a circular buffer - when adding new documents after the size limit is reached, old documents are removed.

    I would like to have an option for the collection, where this behavior can be changed - instead of removing old documents, the insert should fail with a specific error (eg: collection full). This would allow implementing log-rotation, by creating a new collection whenever the old one is full.

    My motivation:
    I have two services, one creating documents (events), and another one processing them. I'm looking for a reliable way to:
    - process all documents from start, without…

  18. placement of mongosh,mongo tools and mongo binary inside core bin

    Hi Team,
    Hope you are doing great!
    Didn't understand the purpose of keeping mongosh,mongo tools and mongo binary separately, can't this be place in a single rpm/tar file so that it can be easy the installation process.
    As per the current :
    Mongo binary location :

    /var/lib/mongodb-mms-automation/mongodb-linux-x86_64-6.0.8-ent/bin

    Mongo Tools location :

    /var/lib/mongodb-mms-automation/mongodb-database-tools-linux-x86_64-100.7.4/bin

    Mongosh location :

    need to keep this file in separate location and access the mongodh. mongosh-1.10.1-linux-x64.tgz

    Thank you

  19. When was last backup/mongodump ran on databases or database backup history

    How can get detail of last backup was taken using query. Its very hard to get into log file and see the history of mongodump. Just like other database tool mongodump history can be retrieved via query instead mongo log file.

    I know get the detail from ops manager if using enterprise only but what if we are using community edition.

    If you include this feature it will very helpful for DBA to get the details juts like other database tools available in market.

  20. Allow rotation of Arbiter TLS certificates when authentication is enabled

    Mongo arbiters do not support using db.rotateCertificates(), because they do not possess the internal table of user and role mappings used for authentication.

    Add functionality to enable rotation of these certificates.
