  1. collection-level users should be able to list their collections

    Currently users with collection-specific read or read/write permissions are not authorized to perform the following commands:

    db.listCollections()
    show collections
    db.getCollectionNames()

    This impacts the shell (and also third party tools that won't let users access their permitted collections because the list of collections is blocked in the first place)

    Suggestion:

    Users with collection-specific read or read/write permissions should be able to run the above commands and the result would only present the collections for which the user has some read or write privileges (instead of blocking everything).

  2. CSFLE - Enable aggregation stages for non-encrypted collections

    When encrypting any collection with CSFLE, aggregation is not allowed on non-encrypted collections.

    The official recommendation is to maintain 2 clients: 1 for CSFLE and 1 for when aggregation is needed. How is this an acceptable solution?

  3. Preserve field order in $merge

    Filed on behalf of https://jira.mongodb.org/browse/SERVER-63853:

    A variety of formats require strict adherence to the sequence of fields, such as bioinformatics

    Files of such formats are often very large and contain nested structures, so it is convenient to use them as collections. But to keep the data belonging to the above specs, it is necessary to keep the arrangement of the fields. Unfortunately, aggregations with saving results to another DB lose original arrangement.

  4. Tiered TTL for time series collection based on granularity

    Currently time series collections have a single TTL across all inherent granularities. It would be great to specify a TTL for each granularity. For example:

    For seconds: 1 week
    For hours: 1 month
    Others: never

    Course information should be held longer than finer information in some cases - currently they all fall under the main TTL specified.

  5. support $lookup for update aggregation

    We frequently denormalise either full documents or subsets to different documents in order to speed up reading, create indexes or paginate/sort on fields.

    Consider a user collection and a task collection, if a task can be assigned to the user, it makes sense to just put the user document on the task they are assigned. But an update to a user now requires you to update the user both in the user collection and all tasks with that user in the tasks collection.

    This can be achieved but does introduce some complexity, however the introduction of updates using aggregation pipelines…

  7. Provide a KRB5_KTNAME setParameter or other config setting

    The Kerberos keytab file is specified in the KRB5_KTNAME environment variable.

    Could a setParameter or other config file setting "krb5KtName" be provided to allow this to be set?

  9. Ability to replicate the data within a cluster to another cluster

    Two different scenarios. One scenario is to have a DR cluster. 2 independant clusters that are one way synced. As of right now, a custom CDC solution (custom code + Kafka) is needed to achieve this.
    Another is because of latency and the requirement for data to be stored in 2 different data center, 2 indepentant mongoDB clusters that are two way synced. As of right now, a custom CDC solution (custom code + Kafka) is needed to achieve this.

  10. Record running queries at the time of a failover

    I recently observed some failovers in a replica set that may have been related to long-running queries. However, since these queries happened only sporadically, it was hard to track them down. Since the queries didn't finish, they weren't present in the logs at the time of the crash.

    It would be useful if it could be possible to somehow capture the long-running queries that were running at the time that something went wrong. I recognize that this is potentially impossible, since once something has gone wrong it can be difficult to do anything.

    We ended up being able to diagnose…

  12. Document known breaking change in JavaScript Engine

    If a new version of MongoDB will include a new version of MozJS (ex https://jira.mongodb.org/browse/SERVER-29286) and this version will break any existing scripts it would be ideal if this was documented.

    For example, with MongoDB 4.2 "value".contains() no longer worked in scripts and had to be converted to "value".includes()

  15. Aggregate $accumulator 'Combine' stage for sharded collections

    After the ‘accumulate’ stage has run against each document on a shard it would be extremely useful to run a script on the shard against the state to reduce the state down to something smaller before passing the final state over the network back to mongos for the ‘merge’. (Over in the Elastic camp they call this the ‘combine_script’).

    Scenario:
    I have a customer orders database sharded by the Customer ID (meaning all data relating to any specific customer is kept on the same shard - so customers don’t need to be ‘merged’ between shards). I can write an accumulator…

  16. Assign MongoDB roles to LDAP users

    I would like to create a softlab and therefore give the possibility to a user to create collections in a database which is dedicated to him.

    Currently, to do that I need to :
    1. create a single-member LDAP group for each user
    2. map this group to a MongoDB role authorizing the user's database.

    Create a group with a single member is conceptually useless. I want to avoid step 1.

    My feature request : add the ability to assign MongoDB roles to LDAP users as well as groups.

    Regards,
    Jerome

  18. Allow collection collation to be editable

    Collation of a collection can be set at creation time only. It would be useful to edit these fields to avoid creating an entire new collection and copying the collection over.

  19. Validation for referential integrity

    Currently, with the JSON Schema validation, we are able to limit the values for a field using enumerations. However, we need to have a way to limit the values to those entered in another collection.

  20. Add Event Stream Features (Apache Kafka, NATS Streaming)

    I thought it would be great if mongodb can support an event streaming(event bus) feature.
    Existing popular event streaming services(AWS Kinesis, NATS Streaming, Apache Kafka) can persist data which is somewhat like a database.

    Its great for debugging, data logging for later uses such as machine learning. Since I can see the full flow of the data and its changes.

    But there are two downside with most even streaming services.
    1. Its very difficult to query the data.
    2. "Eventual Consistency" issue when dealing programmatic errors(bugs). Most event streams have this nice feature, which keeps sending the same event to…
