Provide global collection-aggregated latency stats
The global latency stats Server Status section currently aggregates all the latency information known to the server.
We have a need for the same information except aggregated by collection.
The actual command: db.serverStatus().opLatencies.

$lookup with the option to return only the first element
Often I have a $lookup and the next stage is a $addFields { $first: "" }} because I know the lookup will return only one entry. It'd be nice to have this option directly in the lookup, so it'd return the first object instead of an array. Thanks!

When using EA, auto update the list of cluster node members similar to what happens within Atlas
As we add new nodes, it requires us to update the URI. Would like a way to have this automatically update.

Would like the ability to restore a single zone based shard
If the idea that data is stored within a region (via zone based sharding) and they are "just" replica sets, why can't we just restore a single shard? Right now we have to restore the entire cluster.

Pass document field to $loolup.from and $lookup.as
Suppose I have collection of documents { entityId, entity }, where entity is names of other collections I would like to make aggregation with lookup and be able to pass entity value to $lookup from and as
db.collection.aggregation([{ $lookup: { from: '$entity', let: { entityId: '$entityId' }, pipeline: [{ $match: { $expr: { $eq: ['$_id', '$$entityId'] } } }], as: '$entity' } }])
As of mongo v4.4.4 that seems not working.

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()

Create and use db links in Mongodb
Allow Mongodb to access an external database for:
1.select identifiers on an external rdbms (ex: postgres, sqls, oracle, ...)
2.use these identifiers to perform aggregations in MongodbCurrently, it is necessary to use a third-party tool that connects to several data sources to perform these actions.
The idea is to be able to perform these "joins" only in Mongodb CLI.Regards,

Ability to create the resume token based on oplog item
CHoose an oplog event to set the resume token for, instead of needing to run the change stream for system to create a resume token
Why: Concerns about many stream re-reading a full oplog if failure before finding first event

Add build for Linux Alpine and Debian
A build in ARM support (Apple M1) for Alpine Linux (or Debian) is needed to run the mongocryptd process. Currently the official node docker images are available only in Alpine and Debian.

Allow custom autoscaling policies
Currently this is the following autoscaling policy in mongo:
Please note, if the next highest cluster tier is within your Maximum Cluster Size range, Atlas scales the cluster up to the next tier if one of the following is true for any node in the cluster:
Average CPU Utilization has exceeded 75% for the past hour, or
Memory Utilization has exceeded 75% for the past hour.The feature request is to allow a DBA to setup custom autoscaling policy

log connection string used by application to connect
there are multiple options to connect to mongo: you can connect to specific node or you can connect to the whole replicaset etc...
if DBA does not have access to source code - it's not possible to validate if application properly configured and connects to replicaset.it would be nice to let mongoDB dump to mongod.log used connection string and/or details how exactly client sessions is connected to mongo.

Support split documents on disk
As an application's functionality grows, if kept unchecked it is easy for average document sizes to grow simultaneously.
Large documents can have a significant impact on the performance of MongoDB. However, often the application doesn't actually need the entire document to service a request. Likewise, often queries are sent to MongoDB with a projection, excluding substantial (in terms of byte size) parts of the document.
MongoDB has no ability to optimise these projections (except for covered queries which are not always practical).
MongoDB should provide the ability to specify a "split" in a document such that the query planner can…

Have a role that allows that user to control the schema of a collection
As a DBA or Data Architect, I want to be able to enforce data governance policies like schema control. Users of MongoDB cannot change the schema however DBA or named individuals have the ability to change the schema.

Low latency Change Stream for Global Cluster in Atlas
our event-driven applications need to publish events to Kafka triggered by Change Stream feature. It works perfect in replicaset MongoDB cluster.
However, after migrating to Global Cluster in Atlas, the Change Stream cannot keep low latency because of ordering reason among shards.
The latency may go up to 20 seconds when for a single change event.It would be nice if application can receive Change Stream from the single shard only (not care about ordering among shards) to prevent latency.
The idea is to pass "location" options when starting the Change Stream cursor.

updateMany limit
When porting an application backend from an RDBMS to MongoDB, we've spoken to two people who've are looking for a way to specify a limit on the number of documents in .updateMany(). I understand the behavior cannot be defined on a sharded cluster, but if we had a way to do this on an unsharded collection, that would help when dealing with these teams.

Database users should be able to change their own passwords
Currently, there is no way for Database Users to manage their own passwords, (even if they are atlasAdmin@admin). Moreover, as a Project Owner, I cannot create a role that allows them to do so, e.g.:
use admin db.createRole( { role: "changeOwnPasswordRole", privileges: [ { resource: { db: "", collection: ""}, actions: [ "changeOwnPassword"] } ], roles: [] } )As such, changing passwords always requires a Project Owner setting the new password and sharing it with the Database User. This is a problem, because user-password combinations known by more than one person do not serve as proof of identity.
