Uses of AbstractResourceManagerTask in com.bigdata.resources

Subclasses of AbstractResourceManagerTask in com.bigdata.resources

Modifier and Type	Class and Description
class	AbstractAtomicUpdateTask<T> Abstract base class for tasks responsible for the atomic update of the view of an index partition.
class	AbstractPrepareTask<T> Base class for the prepare phase which reads on the old journal.
class	CompactingMergeTask Task builds an IndexSegment from the fused view of an index partition as of some historical timestamp and then atomically updates the view (aka a compacting merge).
protected static class	CompactingMergeTask.AtomicUpdateCompactingMergeTask The source view is pre-overflow (the last writes are on the old journal) while the current view is post-overflow (reflects writes made since overflow).
class	IncrementalBuildTask Task builds an IndexSegment from the mutable BTree and zero or more additional sources in the index partition view and then atomically updates the view (aka an incremental build).
protected static class	IncrementalBuildTask.AtomicUpdateIncrementalBuildTask The source is an IndexSegment that was built from the mutable BTree associated with the lastCommitTime on old journal of some index partition.
class	JoinIndexPartitionTask Task joins one or more index partitions and should be invoked when their is strong evidence that the index partitions have shrunk enough to warrant their being combined into a single index partition.
protected static class	JoinIndexPartitionTask.AtomicUpdateJoinIndexPartition Task performs an atomic update of the index partition view definitions on the live journal and the MetadataIndex, thereby putting into effect the changes made by a JoinIndexPartitionTask.
class	MoveTask Task moves an index partition to another IDataService.
protected static class	MoveTask.AtomicUpdate Moves an index partition from this data service to another data service.
class	ScatterSplitTask Task splits an index partition into N equal sized index partitions and scatters those index partitions across data services in the federation.
class	SplitIndexPartitionTask Task splits an index partition which is a compact view (no more than one journal and one index segment) and should be invoked when the size of the index segment on the disk exceeds the nominal size of an index partition.
protected static class	SplitIndexPartitionTask.AtomicUpdateSplitIndexPartitionTask An ITx.UNISOLATED operation that splits the live index using the same Split points, generating new index partitions with new partition identifiers.
class	SplitTailTask Splits the tail of an index partition and optionally submits a task to move the tail to a target data service specified by the caller.
protected static class	SplitUtility.BuildIndexSegmentSplitTask Task used to build an IndexSegment from a restricted key-range of an index during a SplitIndexPartitionTask.
