Support hex conversion and binary operators in aggregation framework
The aggregation framework lacks function for HEX <-> Number conversion and binary operations. Such functions are common in almost every programming language.
Typically and most required operations would be:
- convert Int/Long to Hex
- convert Hex to Int/Long
- Create BinData from Hex string
- Get Hex string of BinData
- Binary AND
- Binary OR
- Binary XOR
- Binary NOT (i.e. complement)
Some of these functions are available in mongo shell or in Bitwise Query Operators but they do not exist in aggregation framework.
For details see https://jira.mongodb.org/browse/SERVER-55386
This request becomes more urgent, because starting in MongoDB 8.0, server-side JavaScript functions ($accumulator, $function, $where) are…

$sort should allow 0 as argument meaning "no sort"
The $sort operator and aggregation stage should allow 0 (possibly also null) as an argument for the field sort order, meaning, "Don't sort."
This allows a variable to be passed in that can conditionally skip the sort operation, in addition to the present specification, in which a variable can only choose ascending or descending sort.1 vote -
Easier way to troubleshoot storage use size discrepancy across nodes in the same replica set
While initial sync may potentially help on this topic, it would be great if the product has any easier way to identify the cause of significantly different storage use size (so to give a better confidence if initial sync is going to help).

Feature to perform Machine Learning predictive analysis and classification in MongoDB
I want to bring the machine learning compute and predictive analysis into MongoDB atlas. Instead of ETL my data out of Atlas to achieve this, I will reduce my architectural complexity by having an aggregation operator that does this on my documents stored in Atlas.

Parallelize unionWith
Today $unionWith aggregation command is executed sequentially. EG first we query collection A and then collection B and then the union occurs.
The process should be parallelized so the query part will run in parallel while the union will be done as best effort tree merge try to speed up the overall Elapsed Time of the query1 vote -
Scheduled stepdown for smoother primary election
Stepdown is a great tool that allows us to keep clusters operating smoothly. We use it for example when we want to perform some maintenance work on the host where the primary is currently running, to perform a rolling upgrade, and in many other cases we need to switch the primary to another node.
While usually electing a new primary is fast enough, for clusters with very high write traffic, it sometimes unfortunately leads to write errors on the application side. The reason is that drivers need to disconnect from the previous primary and connect to the new one, and…

Write parts of database engine in ZIG
Zig is a zero-dependency, drop-in C/C++ compiler that supports cross-compilation out-of-the-box. Implementing some parts of MongoDB database engine core in ZIG might brings some performance improvements.

Aggregations should allow an empty sort stage instead of returning an error
When you run an aggregation pipeline that contains an empty sort stage (like
{"$sort": {}}) MongoDB returns the error message "$sort stage must have at least one sort key". It would be really helpful if such a stage would work and simply not apply any sorting at all.For one this would be more consistent with a find operation (e.g.
db.runCommand({"find": "test", "sort": {}})ordb.test.find({}, {}, {"sort": {}})) which does not return an error but simply does not sort the results. More importantly it would also make it easier for developers and frameworks to dynamically generate the…1 vote -
allow mongosync to migrate few field from source to destination for collection in database
right now mongosync will migrate all the fields from source to destination based on filter or non filter setting but there is no way to move few field out of all field for all document
to migrate few field from source to destination for collection in database with default primary key field (_ID )

TTL index activity statistics
Dear all,
Presently, there is no visibility or tracking of TTL index activity: no data available to the user to see how much data and how often has been deleted. I suggest having a separate “dictionary” collection with statistics for all TTL indexes with pre-defined data retention (aka last month).
Thank you for looking at that.
Regards, Marina.

Sorting support on Array fields.
Presently, I'm attempting to arrange(sort) the documents within my collection based on a key nested within an array object. However, sorting isn't functioning as expected in this scenario.
A proper explanation with example is here what I mean.

JSON
I'm converting a lot of data for export from MongoDB -> Postgresql
I would like an aggregation function to convert an object to JSON
{
"$addField": {
"_id": true,
"json": {
'$convert': {
'input': '$subdocument',
'to': 'json', # // Idealy, +1 for msgpack https://msgpack.org/
}
}
}
}thus object.json would be a STRING "{abc: true}"
FYI: Postgresql supports JSON(B) in it's field structures: https://www.postgresql.org/docs/current/datatype-json.html

Self-Managed Computed Collections
This feature would enable MongoDB to automatically generate common patterns by computing entire collections. A particularly useful application would be the ability to identify duplicate fields within a collection and create a computed collection that groups all possible duplicate together.
Sometimes, a field is duplicated between two documents, while another field in the same document is duplicated across seven other documents. Each of these seven documents might have fields that are duplicated in yet other documents, leading to a vast iteration in search of possibilities.
Having MongoDB abstract all this logic in a performant manner to create computed collections would…

Fine-tune the update privilege action
We want our devs to be able to update docs, but only one at a time. If they need to update a bunch together, they should check in with the DBA. Right now, we can't fine-tune the update permissions like we'd prefer, so we're looking into ways to make that happen. This will help us manage document updates better and add a layer of security.

AWS IAM Role integration with MongoDB On premise
We are planning to integrate AWS IAM Roles/Users with MongoDB On-premise for password-less authentication. So the authentication happens through IAM Profile. However, we noticed currently MongoDB on-premise doesn't support AWS IAM Role integration. This is a blocker. We want the authentication would happen through AWS IAM Profile rather than Standard Credentials.
This would eliminate or significantly reduce the use of Database Credentials while tightly integrating with AWS Services. Simultaneously, applications can securely connect to MongoDB via AWS Profile.1 vote
