Wellington Chevreuil updated HBASE-25392:
-----------------------------------------
Release Note:
Introduces the DirectStoreCompactor, an extension of DefaultCompactor, which
writes compactions result files straight into the store directory, rather than
the temp dir approach implemented by DefaultCompactor.
In commitCompaction, it does not perform any renames. Should always be used
together with PersistedStoreEngine proposed in HBASE-25395 and
DirectStoreFlusher proposed in HBASE-25391, as it's up for StoreEngine
implementations keep tracking of valid store files.
To enable this, the following properties must be set in RS configuration:
<property>
<name>hbase.storefile.tracking.persist.enabled</name><value>true</value>
</property>
<property>
<name>hbase.hstore.engine.class</name>
<value>org.apache.hadoop.hbase.regionserver.PersistedStoreEngine</value>
</property>
<property>
<name>hbase.regionserver.store.flush.context.class</name><value>org.apache.hadoop.hbase.regionserver.DirectStoreFlushContext</value>
</property>
<property>
<name>hbase.hstore.defaultengine.storeflusher.class</name><value>org.apache.hadoop.hbase.regionserver.DirectStoreFlusher</value></property>
<property>
<name>hbase.hstore.defaultengine.compactor.class</name>
<value>org.apache.hadoop.hbase.regionserver.compactions.DirectStoreCompactor</value>
</property>
> Direct insert compacted HFiles into data directory.
