v0.5.0

v0.5.0

Highlights

Follower to leader replication

• The write API (Put, DeleteRange, Txn) is now available on follower cluster nodes as well.
• The API provides read after write guarantee by relying on backpropagation from the leader.

Dynamic tables management

• Tables now could be managed dynamically during the runtime of the server using newly provided regatta.v1.Tables API.
• Tables API could be secured by an API token using tables.token configuration value.

Security

• API port now supports mTLS
• API port mTLS can verify Hostname or CN in presented certificate.
• Follower to Leader mTLS can now verify Hostname or CN in presented certificate.

Improvements

• Improve on API allocations when deserializing gRPC messages.
• Support zstd API compression.
• Removed obsolete table manager cache that could have caused hard to debug race conditions.
• Bump to Go 1.22.

Deprecations

• tables.names and tables.delete configuration values were deprecated and will be removed in future releases.

Bugfixes

• Proper authentication of maintenance.v1.Backup/Restore API endpoint.
• When table is deleted in the leader cluster the followers will gracefully handle the situation by deleting the table locally and stopping the replication.
• Fixed potential Engine deadlock when shutting down the server.
