Class HStore
java.lang.Object
org.apache.hadoop.hbase.HStore
- All Implemented Interfaces:
- HConstants
public class HStore
- extends Object
- implements HConstants
HStore maintains a bunch of data files. It is responsible for maintaining
the memory/file hierarchy and for periodic flushes to disk and compacting
edits to the file.
Locking and transactions are handled at a higher level. This API should not
be called directly by any writer, but rather by an HRegion manager.
