public class InnerSpaceCompactionExceptionHandler
extends Object

This class is used to handle exception (including OOM error) occurred during compaction. The allowCompaction flag in TsFileManager may be set to false if exception cannot be handled correctly(such as OOM during handling exception), after which the subsequent compaction in this storage group will not be carried out. Under some serious circumstances(such as data lost), the system will be set to read-only.
