Uses of DataSourceMetadata in org.apache.druid.indexing.overlord

Classes in org.apache.druid.indexing.overlord that implement DataSourceMetadata

Modifier and Type	Class	Description
final class	ObjectMetadata

Methods in org.apache.druid.indexing.overlord that return DataSourceMetadata

Modifier and Type	Method	Description
DataSourceMetadata	DataSourceMetadata.asStartMetadata()	As in IndexerMetadataStorageCoordinator.commitSegments(java.util.Set<org.apache.druid.timeline.DataSegment>, org.apache.druid.segment.SegmentSchemaMapping), this class can represent start and end of a sequence.
DataSourceMetadata	ObjectMetadata.asStartMetadata()
DataSourceMetadata	DataSourceMetadata.minus(DataSourceMetadata other)	Returns a copy of this instance with "other" subtracted.
DataSourceMetadata	ObjectMetadata.minus(DataSourceMetadata other)
DataSourceMetadata	DataSourceMetadata.plus(DataSourceMetadata other)	Returns a copy of this instance with "other" merged in.
DataSourceMetadata	ObjectMetadata.plus(DataSourceMetadata other)
DataSourceMetadata	IndexerMetadataStorageCoordinator.retrieveDataSourceMetadata(String supervisorId)	Retrieves DataSourceMetadata entry for supervisorId from the metadata store.

Methods in org.apache.druid.indexing.overlord with parameters of type DataSourceMetadata

Modifier and Type	Method	Description
SegmentPublishResult	IndexerMetadataStorageCoordinator.commitAppendSegmentsAndMetadata(Set<DataSegment> appendSegments, Map<DataSegment,ReplaceTaskLock> appendSegmentToReplaceLock, String supervisorId, DataSourceMetadata startMetadata, DataSourceMetadata endMetadata, String taskAllocatorId, SegmentSchemaMapping segmentSchemaMapping)	Commits segments created by an APPEND task.
SegmentPublishResult	IndexerMetadataStorageCoordinator.commitMetadataOnly(String supervisorId, String dataSource, DataSourceMetadata startMetadata, DataSourceMetadata endMetadata)	Similar to IndexerMetadataStorageCoordinator.commitSegments(java.util.Set<org.apache.druid.timeline.DataSegment>, org.apache.druid.segment.SegmentSchemaMapping), but meant for streaming ingestion tasks for handling the case where the task ingested no records and created no segments, but still needs to update the metadata with the progress that the task made.
SegmentPublishResult	IndexerMetadataStorageCoordinator.commitSegmentsAndMetadata(Set<DataSegment> segments, String supervisorId, DataSourceMetadata startMetadata, DataSourceMetadata endMetadata, SegmentSchemaMapping segmentSchemaMapping)	Attempts to insert a set of segments and corresponding schema to the metadata storage.
boolean	IndexerMetadataStorageCoordinator.insertDataSourceMetadata(String supervisorId, DataSourceMetadata dataSourceMetadata)	Insert DataSourceMetadata entry for supervisorId.
boolean	DataSourceMetadata.matches(DataSourceMetadata other)	Returns true if any information present in this instance matches analogous information from "other" and so they are conflict-free.
boolean	ObjectMetadata.matches(DataSourceMetadata other)
DataSourceMetadata	DataSourceMetadata.minus(DataSourceMetadata other)	Returns a copy of this instance with "other" subtracted.
DataSourceMetadata	ObjectMetadata.minus(DataSourceMetadata other)
DataSourceMetadata	DataSourceMetadata.plus(DataSourceMetadata other)	Returns a copy of this instance with "other" merged in.
DataSourceMetadata	ObjectMetadata.plus(DataSourceMetadata other)
boolean	IndexerMetadataStorageCoordinator.resetDataSourceMetadata(String supervisorId, DataSourceMetadata dataSourceMetadata)	Resets DataSourceMetadata entry for supervisorId to the one supplied.
static void	IndexerMetadataStorageCoordinator.validateDataSourceMetadata(String supervisorId, DataSourceMetadata startMetadata, DataSourceMetadata endMetadata)	Validates the given supervisorId and given metadata to ensure that start/end metadata non-null implies supervisor ID is non-null.

Uses of DataSourceMetadata in org.apache.druid.indexing.overlord.supervisor

Methods in org.apache.druid.indexing.overlord.supervisor with parameters of type DataSourceMetadata

Modifier and Type	Method	Description
void	StreamSupervisor.checkpoint(int taskGroupId, DataSourceMetadata checkpointMetadata)	The definition of checkpoint is not very strict as currently it does not affect data or control path.
void	Supervisor.reset(DataSourceMetadata dataSourceMetadata)	Resets any stored metadata by the supervisor.
void	StreamSupervisor.resetOffsets(DataSourceMetadata resetDataSourceMetadata)	Reset offsets with provided dataSource metadata.

Uses of DataSourceMetadata in org.apache.druid.metadata

SegmentPublishResult	IndexerSQLMetadataStorageCoordinator.commitMetadataOnly(String supervisorId, String dataSource, DataSourceMetadata startMetadata, DataSourceMetadata endMetadata)
SegmentPublishResult	IndexerSQLMetadataStorageCoordinator.commitSegmentsAndMetadata(Set<DataSegment> segments, String supervisorId, DataSourceMetadata startMetadata, DataSourceMetadata endMetadata, SegmentSchemaMapping segmentSchemaMapping)
