pub fn new( query_engine: QueryEngineRef, runtime: Runtime, event_listener: RegionServerEventListenerRef, flight_compression: FlightCompression, ) -> Self
pub fn with_table_provider( query_engine: QueryEngineRef, runtime: Runtime, event_listener: RegionServerEventListenerRef, table_provider_factory: TableProviderFactoryRef, max_concurrent_queries: usize, concurrent_query_limiter_timeout: Duration, flight_compression: FlightCompression, ) -> Self
pub fn register_engine(&mut self, engine: RegionEngineRef)
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>>
pub async fn handle_request( &self, region_id: RegionId, request: RegionRequest, ) -> Result<RegionResponse>
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.
pub fn is_region_leader(&self, region_id: RegionId) -> Option<bool>
pub fn set_region_role( &self, region_id: RegionId, role: RegionRole, ) -> Result<()>
Sourcepub async fn set_region_role_state_gracefully(
&self,
region_id: RegionId,
state: SettableRegionRoleState,
) -> 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.
pub fn runtime(&self) -> Runtime
pub fn region_statistic(&self, region_id: RegionId) -> Option<RegionStatistic>
async fn handle_batch_ddl_requests( &self, request: Body, ) -> Result<RegionResponse>
async fn handle_requests_in_parallel( &self, request: Body, ) -> Result<RegionResponse>

async fn handle_sync_region_request( &self, request: &SyncRequest, ) -> Result<RegionResponse>
Sourceasync fn handle_list_metadata_request(
&self,
request: &ListMetadataRequest,
) -> Result<RegionResponse>
async fn handle_list_metadata_request( &self, request: &ListMetadataRequest, ) -> Result<RegionResponse>
Handles the ListMetadata request and retrieves metadata for specified regions.
Returns the results as a JSON-serialized list in the RegionResponse. It serializes
non-existing regions as null
.
Sourcepub async fn sync_region(
&self,
region_id: RegionId,
manifest_info: RegionManifestInfo,
) -> Result<()>
pub async fn sync_region( &self, region_id: RegionId, manifest_info: RegionManifestInfo, ) -> Result<()>
Sync region manifest and registers new opened logical regions.
