Package org.apache.iotdb.db.engine.compaction.performer

Interface ICompactionPerformer

All Known Subinterfaces:

ICrossCompactionPerformer, ISeqCompactionPerformer, IUnseqCompactionPerformer

All Known Implementing Classes:

ReadChunkCompactionPerformer, ReadPointCompactionPerformer

public interface ICompactionPerformer

CompactionPerformer is used to compact multiple files into one or multiple files. Different performers may use different implementation to achieve this goal. Some may read chunk directly from tsfile, and some may using query tools to read data point by point from tsfile. Notice, not all kinds of Performer can be used for all kinds of compaction tasks!
