Sourcepub fn find_engine(
&self,
region_id: RegionId,
) -> Result<Option<RegionEngineRef>>
pub fn find_engine( &self, region_id: RegionId, ) -> Result<Option<RegionEngineRef>>
Finds the region’s engine by its id. If the region is not ready, returns None
.
pub async fn handle_batch_open_requests( &self, parallelism: usize, requests: Vec<(RegionId, RegionOpenRequest)>, ) -> Result<Vec<RegionId>>

Sourceasync fn table_provider(
&self,
region_id: RegionId,
ctx: Option<&QueryContext>,
) -> Result<Arc<dyn TableProvider>>
async fn table_provider( &self, region_id: RegionId, ctx: Option<&QueryContext>, ) -> Result<Arc<dyn TableProvider>>
Returns a table provider for the region. Will set snapshot sequence if available in the context.
Sourcepub async fn handle_remote_read(
&self,
request: QueryRequest,
) -> Result<SendableRecordBatchStream>
pub async fn handle_remote_read( &self, request: QueryRequest, ) -> Result<SendableRecordBatchStream>
Handle reads from remote. They’re often query requests received by our Arrow Flight service.
pub async fn handle_read( &self, request: QueryRequest, ) -> Result<SendableRecordBatchStream>
Sourcepub fn reportable_regions(&self) -> Vec<RegionStat>
pub fn reportable_regions(&self) -> Vec<RegionStat>
Returns all opened and reportable regions.
Notes: except all metrics regions.

) -> Result<SetRegionRoleStateResponse>
pub async fn set_region_role_state_gracefully( &self, region_id: RegionId, state: SettableRegionRoleState, ) -> Result<SetRegionRoleStateResponse>
Set region role state gracefully.
For SettableRegionRoleState::Follower: After the call returns, the engine ensures that no further write or flush operations will succeed in this region.
For SettableRegionRoleState::DowngradingLeader: After the call returns, the engine ensures that no further write operations will succeed in this region.
