Cloning User/Roles along with Database
When cloning a Database it would be helpful if User/Roles could be cloned directly as well and carried over.

Tag-aware permissions to control access to analytics nodes
MongoDB has the great future of Workload Isolation based on node tags: we can add nodes tagged for analytics or reporting and then configure the same tag for this type of connections so that they do not interfere with the main operational workload.
But it is the responsibility of the BI/Data Scientist/Analyst to properly configure the connection: it cannot be enforced in a centralised way. It would be great if MongoDB permissions could be "tag aware", and allow access for a particular user only to some nodes of the 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.

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.

2dindex
geoIntersect queries on spherical geometries are not adapted to our use case. Our need is to retrieve a list of tiles intersecting a given area of interest (AOI) in a flat 2d geometry.
Classical geo-spatial databases (PostGIS and Oracle Spatial) support this kind of approach at no extra cost and we would expect the same from MongoDB.
In MongoDB , using a 2dsphere index forces us to implement a workaround adding an artificial margin to the AOI and making a post-processing to remove false positives. See attached slides for explanations.

Diacritic insensitive contains search on a single field
I would like to perform a "contains" query on a single text field in a case insensitive and diacritic insensitive way. I would like the query to have the performance of the field being in a text index by itself (assuming that this gives the maximum speed).
It is usually the case that the text index already exists for multiple fields. This means that a text search then has to be combined with a complicated (to make it diacritic insensitive) regex expression to find the correct results.

Add an option for $addToSet to use a specific field in the array for uniqueness
Currently, the $addToSet for upserting to an array checks for object equality (when the array elements are objects). We sometimes need to check for uniqueness based on a specific field of the object rather than the object as a whole, and the only way to do this is to force single-threaded operation and to use $pull and $push.
If there is a way to specify the field to check uniqueness for the $addToSet , we would be able to perform writes normally.

Extended JSON
Add support for Extended JSON (EJSON. For example, {$date: "2021-01-01T00:00:00.000Z"} ) such that we do not have to resort to using the ISODate helper function in the MongoDB Shell and in Compass.

Arrow function support
Is there any plan to implement arrow functions support?
The current way to use functions (BSON type 13) is using traditional javascript functions:function() {
...
emit(key, value);
}
It would be great to support also arrow functions:
() => {
...
emit(key, value);
}

4.4 to the EU on regular instance for development!
I work on mongodb in the EU.. i want to use the atlas search but i also need some features of v4.4
In development and for general everyday projects where our clients don't have large user bases we generally go for M2 instances.. affordable while offering full text search.
The release of 4.4 is almost half a year old.. when will we see 4.4 released to the EU of regular M2 instances??

Bundle rest service together DB
As per current industry practice, REST/Json became standard way to deal with the data between the FE application and Backend DB. So if REST the server/service is bundled with DB it would eliminate the need of a middleware tier in most cases.
It means we can directly fetch data from a frontend application using REST/Json from mongoDB without requiring a thirdparty service.

Conditional TTL index
In case of auto purging sometimes user might want to ensure data has been archived before purging. If conditional TTL was allowed user could set value of a field to indicate document has been archived and then db can purge accordingly.

String Json Parser
lately, I imported a big CSV file, containing fields with values of Json object in String format, the simplest way to parse those strings to object it was by doing find().forEach( JSON.pase then update) it taken too much time to update the collection the only think that i have could done to reduce the latency is putting write priority to 0 which isn't very advisable with high throughput of updates, I don't really know for sure I'am not the expert here but working with big data demand a lot of cleaning, and not being able to do the cleaning on…

Ability to view and track collection wise transactions (read,write,success,failures)
We have multiple microservices using the same collection and we'd like to track how many calls come from each, and also understand which transactions are successful or not.
Ultimately this will allow us to understand the MDB usage by each of the microservices.
[setting verbose logging level to 1 and then using these logs to create a dashboard in Splunk doesn't give us enough granularity]1 vote -
Find all geoJSON points within a large collection of polygons. Reference collection in geoWithin.
I would like to be able to find all geoJSON points located within a collection of polygons. My personal goal is to find points located within earth's water bodies. The water bodies are located in their own collection while the geoJSON points are located in a separate collection within the same DB. Mongo's geoWithin function only lets me hard code the polygons, but I would like to reference a collection of polygons.
