v1.18.0 (2024-01-08)

What's Changed

Capped collections

This release adds support for capped collections. They can be created as usual using create command. Both max (maximum number of documents) and size (maximum collection size in bytes) parameters are supported.

Tailable cursors

This release adds support for tailable cursors. Both tailable and awaitData parameters are supported.

OpLog tailing

This release adds support for the basic OpLog functionality. The main supported use case is Meteor's OpLog tailing. Replication is not supported yet.

OpLog collection does not exist by default. To enable OpLog functionality, create a capped collection oplog.rs in the local database. Setting replica set name using --repl-set-name flag / FERRETDB_REPL_SET_NAME environment variable might also be needed.

New Features 🎉

What's Changed

This release provides beta-level support for the SQLite backend. There is some missing functionality, but it is ready for early adopters.

This release provides improved cursor support, enabling commands like find and aggregate to return large data sets much more effectively.

Tigris data users: Please note that this is the last release of FerretDB which includes support for the Tigris backend. Starting from FerretDB v1.6.0, Tigris will not be supported. If you wish to use Tigris, please do not update FerretDB beyond v1.5.0. This and earlier versions of FerretDB with Tigris support will still be available on GitHub.
