New Features

• Introduce clustered servers

  Introduce cluster support in the TypeDB protocol.

  In TypeDB 2.x, each database response carried its own replica list (DatabaseReplicas). In TypeDB 3.x, servers are the unit of replication, and all databases on that server share the replication context.

  • Replace per-database replica discovery with server-level discovery. On connection open, return ServerManager.All.Res (servers with replica status) instead of DatabaseManager.All.Res (databases with replicas).
  • Add servers_get RPC to retrieve the specific server's replica status.
  • Add server_version RPC to retrieve server distribution and version.
  • Remove DatabaseReplicas message. Instead, return Database (name only) instead of DatabaseReplicas (name + replica info). Replica topology is a server-level concern.
  • Replica information is now on Server.ReplicaStatus (replica ID, role, term).

  Breaking: not compatible with previous versions.

Other Improvements

• Upgrade Rust toolchain and update dependencies

  We update Rust toolchain to 1.93.0, as well as dependencies.
