Subclasses of AbstractPrepareTask in com.bigdata.resources

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).
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).
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.
class	MoveTask Task moves an index partition to another IDataService.
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.
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.
