["Wellington Chevreuil (Jira)" <ji...@apache.org>]

     [ https://issues.apache.org/jira/browse/HBASE-25392?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

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.
