add view，index，user，role to mongodb Change Stream
I tested the changeStream of mongodb. The changes of adding view, index, user and role to mongodb are not reflected in changeStream, but the corresponding log can be found in oplog. I have an issue on https://jira.mongodb.org/browse/SERVER-66460 and got it confirmed, but Chris Kelly thinks this should be a feature. Hopes to add this feature in future versions

Change how document size is calculated
Disclaimer: I'm aware that this is a pretty big feature request.
Currently a document has a max size of 16 mb. I'm not suggesting changing that. However, I'm suggesting changing how that size is calculated.
I'm designing a database in which documents have a tree structure. The document will have an array called "nodes", which can hold any number of child nodes. Those nodes can also have arrays of nodes, and so on. It's a simple tree structure.
For major users of my application, that outer document could get pretty big. It's not a problem right now (no users, no…

Make it possible to delete a database via API
It would be nice to be able to delete a database in a replica set via an API call. This would make it easier for CI/CD when deleting clients
Strange thing is that I can delete a complete cluster, but more fine-grained deletion is not possible. like deleting a replica set or only 1 database in a replica set. The most dangerous one is available via API :)1 vote -
Multi-version-intermediate upgrade package
When upgrading the MongoDB server community edition from a very old version to the newest version one cannot skip installing intermediate versions, e. g. version 3.6 -> 4.4 does not work because the database files cannot be auto-migrated and the FeatureCompatibilityVersion is too low on 3.6 (or not existent).
Instead we have to install 3.6 -> 4.0 -> 4.2 -> 4.4 and execute db.adminCommand( { setFeatureCompatibilityVersion: "..." } ) appropriately in between installing each new version.
I propose creating an additional installer package for Linux which takes care of all that to migrate the internal database structure from the installed…

Have an API to have the History of Primary Nodes
Have an API to have the History of Primary Nodes,from the time the Replica set is initiated.I know we can have alerts for Primary switch over,but if we want to analyse the data of elections/primary node for say about last 1 year , an API would help.

Add option to $dayOfWeek to choose between Monday and Sunday
Hi!
I was wondering if you could add an optional parameter to $dayOfWeek that allows you to choose on which day you want the functionality to start counting.
Thanks!

URL Decode `readPreferenceTags`
If a url encoded value is set to readPreferenceTags it will be ignored causing for instance connecting to analytics node impossible from tooling that correctly encodes the urls.
It can look like this for instance:

the profile output in association with the $comment query operator need to have consistency across operations.
I have observed the different profile result with regard to $comment query operator in association with find and update operation respectively as follows;
find operation shows a comment on the command.filter.$comment and the command.comment field in the system.profile collection.
op: 'query',
ns: 'db101.Bets',
command: {
find: 'Bets',
filter: {
_id: ObjectId("61a9db4b3bd34e4f68fb9abc"),
'$comment': 'test-dba'
},
comment: 'test-dba',
lsid: { id: UUID("43ebee67-3184-4ede-9cee-ecca7457861a") },
'$db': 'db101'
},update operation shows a comment only on the command.q.$comment field in the system.profile collection.
op: 'update',
ns: 'db101.Bets',
command: {
q: {
_id: ObjectId("61a9db4b3bd34e4f68fb9abc"),
'$comment': 'test-dba'

Please report mixed-type numeric _id fields in $merge stage error
Posting this idea at the request of one of the Jira users. You can find more technical details about this in the Jira issue:
https://jira.mongodb.org/browse/SERVER-61613
The gist of it is that I may have two collections,
b2andb3, that are not distinguishable in the Mongo Shell, like this:db.b2.find() [ { _id: 1, created: ISODate("2021-11-18T23:16:33.149Z") }, { _id: 2, created: ISODate("2021-11-18T23:16:33.149Z") } ] db.b3.find() [ { _id: 1, created: ISODate("2021-11-18T22:53:02.113Z") }, { _id: 2, created: ISODate("2021-11-18T22:53:02.113Z") } ] ``` When I merge each into a collection `pg` with this syntax:db.pg.aggregate([{$merge: {into: "b3", whenMatched: "merge", whenNotMatched: "fail"}} ]);…

multiple centersphere as a geometry for geowithin
im looking at one of my queries that a system regularly runs and some times we look for records that are within up to 250 different centerspheres, i wornder if we could enable, like geowithin has the ability to support multiple poligons, we could enable multiple centerspheres ,
$match: {{'location':{
"$geoWithin" : {
"$centerSphere" : [[ 14.4321, -9.4321], 2.5232135647961246e-05]
}
}}, {'location':{
"$geoWithin" : {
"$centerSphere" : [[ 14.4321, -9.4321], 2.5232135647961246e-05]
}
}}, ...}
we could do :
```
$match: {'location':{
"$geoWithin" : {
"$centerSpheres" : [
[[ 14.4321, -9.4321], 2.5232135647961246e-05] ,
[[ 14.4321, -9.4321], 2.5232135647961246e-05],

There is a specific collection that I need more performance than others. Is there a way to assign more ram/memory to a specific collection?

Reserve connections to admin users
When the max number of connections is reached, no one can login to the database until some connections are closed or a failover is triggered (killing all the connections).
The admin users should have a few reserved connections so that they can login to the database and take actions, like kill some connections.
