* feat: add relational region engine skeleton and registration Add a read-only relational RegionEngine (create/open/drop lifecycle) and register it as the 4th engine in build_store_engines alongside mito/metric/file. Add a datanode-level test asserting all 4 engines are registered. Signed-off-by: tian1220A <1573612521@qq.com> * feat: add relational connection and idempotent region lifecycle Move ConnectionInfo into relational-engine (DSN parsing + redacted rendering), place the RelationalOptions/RELATIONAL_META_KEY serialization contract in table::requests, make CREATE idempotent by comparing the persisted manifest definition against the incoming request (RegionExists on mismatch), and drop the empty EngineConfig placeholder. Signed-off-by: tian1220A <1573612521@qq.com> * refactor: address review comments on relational region engine - remove connection.rs (only used by its own tests); it will be reintroduced when connection handling is wired up - drop RelationalOptions::version (not validated or used to select a deserialization format) - validate an idempotent create against the existing region definition (region id / schema / primary key / options) and return Unexpected on mismatch, with a reason field on RegionExists - use serde.workspace and remove the empty [features] section - cargo fmt Signed-off-by: tian1220A <1573612521@qq.com> * fix: adapt relational engine to latest main - implement RegionEngine::set_region_role_with_lease (no-op lease, the engine takes no writes so no lease is needed) - pass node_id to build_object_store_manager in the registration test - drop stale url dependency from the relational-engine lock entry Signed-off-by: tian1220A <1573612521@qq.com> * ci: register relational-engine in scope rules Signed-off-by: tian1220A <1573612521@qq.com> * fix: remove table self-dependency from Cargo.lock Signed-off-by: tian1220A <1573612521@qq.com> --------- Signed-off-by: tian1220A <1573612521@qq.com>
