Data Replication from one MongoDB Cluster to another MongoDB Cluster
Create an option for the user to replicate data from one MongoDB Cluster to another MongoDB Cluster inside the account. We don't need to migrate data, I need replicate data from an Production Cluster to an Dev/Test Cluster. Thanks.

Old and New values in change tracking
Change streams currently return only the new version of the documents.
If there were an option that could be set on the collection for the change streams to also return the old version of the document, it would simplify any business logic that requires the old version.

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…

Support throttling the balancer for sharded clusters
As high throughput clusters grow and documents become larger, the MongoDB balancer may begin impacting workloads.
I'd like the ability to throttle the speed at which the balancer or chunk migrator runs such that impact is minimised.

Make IAM database user authentication compatible with AWS SSO
We are in the process of implementing AWS SSO across our Organisation and wanted to tie this in with mongodb-aws for database authentication.
Unfortunately we have been informed the 2 services are not compatible.This would be a really useful add on to improve management of our systems.

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()

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

view on nested array
- It is quite common to have nested array in documents in MongoDB.
- It is also quite common to have to "flatify" those arrays in queries.
Here is an example where we have a collection with consultants and their professional experiences.
```
consultant [{
name:"Toto",
age: 25,
experiences: [{role: "Sofware Engineer",
from: "2010-01-01",
to: "2012-01-01",
company: "CompanyA"}, {
role: "Data Analyst",
from: "2018-01-01",
to: "2020-01-01",
company: "CompanyB"}]
}]
```If we would like to list all experiences at a company during a certain period of time, we would have to do an aggregate query with 3 steps that…

VPC between ATLAS/MongoDB/AWS and Heroku/AWS
Would be a great great feature if we can create a VPC between ATLAS/MongoDB/AWS and Heroku/AWS.
Thanks.

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.
Best Regards
