Hi,
I just got news, that FerretDB 1.18 now has support of OpLog. So I will be trying replace MongoDB 6.x with FerretDB/PostgreSQL or FerretDB/SQLite.

### What should be done? Refs [#24](https://github.com/FerretDB/engineering/i…ssues/24), #2501 They use Meteor which often tails the oplog for performance benefits but tailing the oplog is an optional setting for WeKan defined [here](https://github.com/wekan/wekan/blob/master/docker-compose.yml#L203). It uses Meteor's [poll-and-diff method](https://blog.meteor.com/tuning-meteor-mongo-livedata-for-scalability-13fe9deb8908) by default which just uses find under-the-hood. They also use [GridFS](https://www.mongodb.com/docs/manual/core/gridfs/) to store avatars and attachments. https://github.com/wekan/wekan/tree/master/models ```[tasklist] ### Tasks - [ ] #826 - [ ] #825 - [ ] #1428 - [ ] #1423 - [ ] #1439 - [ ] #2013 - [ ] #1432 - [ ] #1467 - [ ] #1427 - [ ] #76 - [ ] #1754 - [ ] #2448 ```

When I asked for Meteor FerretDB examples, I got some replies here. Please help testing. Thanks!

From podcasts of Meteor 3 and Storyteller, I got some info that:

Upcoming MongoDB is making OpLog private, so Meteor team is thinking about changing to Change Streams
MongoDB is deprecating GridFS

I have not got FerretDB working yet, there was some problems with some database queries. While FerretDB has OpLog, I’ll try to find is there info about Change Streams in FerretDb.
