java.lang.Object

org.apache.iotdb.db.engine.compaction.CompactionScheduler

public class CompactionScheduler
extends Object

CompactionScheduler schedules and submits the compaction task periodically, and it counts the total number of running compaction task. There are three compaction strategy: BALANCE, INNER_CROSS, CROSS_INNER. Difference strategies will lead to different compaction preferences. For different types of compaction task(e.g. InnerSpaceCompaction), CompactionScheduler will call the corresponding selector according to the compaction machanism of the task(e.g. LevelCompaction, SizeTiredCompaction), and the selection and submission process is carried out in the selectAndSubmit() in selector.
