  1. Ability to see historical `serverStatus.uptime` counter info on MongoDB Server process

    What is the problem that needs to be solved? Store (historically) serverStatus.uptime counter info on MongoDB Server process, so that it will be possible to track serverStatus.uptime changes through the time.

    Why is it a problem? (the pain) As of now (2020-02-25) there's no way to see historical info of MongoDB Server process restarts since serverStatus.uptime counter is restarted every time MongoDB Server process is restarted. There's no other way (other than going into MongoDB Server process logs) to know if the process was restarted and when it was restarted. If you'd like to calculate MongoDB Server process availability, you'll…

  2. MongoDB 4.2 Distributed Transaction with Arbiter

    Hello.
    We are preparing to introduce MongoDB 4.2 and expect distributed transaction function.

    I read document which arbiter don't be member when use distributed transaction.

    https://docs.mongodb.com/manual/core/transactions/index.html#arbiters

    PSA can do that, but it's weird that it doesn't even work out to PSSA.

    It usually operates as a PSS from an operating point of view, but can temporarily become a PSA in the event of equipment problems.

    Why should there be no Arbiter in the Shard to use Distributed Transaction?
    I can not understand restriction.

    Can you tell me technical reason for not being able to support Distributed Transaction with Arbiter?
    Do…

  3. More verbose information about compact failures in logs

    Recently we had a compact operation fail, and the mongod logs stated this was due to "eviction pressure" on the server. We have learned that this is a failsafe mechanism built into the compact command, but we would like to have a more verbose explanation of this failure mode in the logs to better understand why it failed and steps to remediate the issue.

  4. MongoDB emulator

    From a user - A MongoDB in-memory emulator would help development against MongoDB in a completely isolated way. They deploy self contained applications for developers that don't have any external connections other than MongoDB. The customer found a community project, fongo, that does this, but it is not supported and trails development by a few versions. https://github.com/fakemongo/fongo. I would be happy to connect the users with relevant project managers

  5. Periodic large bulk insert/update all or nothing with instant switchover

    Provide the ability for orgs to update things like large reference data sets periodically. E.g. an ecommerce site updates its product inventory every night at midnight, where even though the inserts or updates may take say 10 minutes to run and complete, the applications do not see the changes until the bulk update finishes. The problem otherwise is currently, the ecommerce app, in this example, may be reading product data partly from yesterday's data and partly from today's changed data, during the 10 minute run. For consistency the application would ideally want to see data from either before the bulk…

  6. Support for wildcards in permission parameters

    Support for wildcards or maybe even regular expressions in the database/collection name of a permission for a custom role.

    We have a multi tennant setup, by storing every customer's data in its own database on the cluster. The applications we build span those databases, but every application has it's own permissions on a collection name bases.

    instead of granting "find" permission to the "products" collection of all databases like "mongodbcom" and "somecompanycom", it would be nice if we coulf configure it like "find" permission to the "products" collection on the database matching /^[a-z]+_[a-z]+$/

  8. Validate Window

    In 4.4 with validate being able to run in the background.

    https://docs.mongodb.com/master/reference/method/db.collection.validate/#behavior

    It would be good to have a "validate window" that would cycle though each collection. Similar to the way a balancing window works in sharding.

  9. Allow validate to use replica tags

    The use case for this is to be able to target a secondaries in different shards.

    If validate accepted tag read preference it could be kicked off from a shell connected to a mongos.

  10. would be helpful, with the online interface, to be able to bulk import collections

    For those whose corporate firewalls do not allow for mongo client access to the free mongo cloud db, it would be extremely helpful to be able to upload a pre-formatted json collection of documents, rather than entering those documents one at a time.

  11. mongo binary utility for slaptest

    Please provide binary for slaptest for Mongo server just like mysqlslap for mysql server. This enables us to test a better index by doing a slap test on server with multiple combinations of indexes by dba itself instead of depending on load tests from application like jmeter load test , soasta load test etc which needs involvement of multiple resources, developers, testers and lot of time.

  12. Use dedicated interface for replication and balancing

    Like many other big database system, MongoDB may support to specify dedicated interfaces for replication and/or for the balancer (sharding)

    Currently you can configure replication sets and shards members only by single hostname/IP-Address, i.e. all data is transmitted over the same network interface.
