Summary: External Configuration for Memory Compaction
Key: HBASE-17294
URL: https://issues.apache.org/jira/browse/HBASE-17294
Project: HBase
Issue Type: Sub-task
Reporter: Eshcar Hillel
We would like to have a single external knob to control memstore compaction.
Possible memstore compaction policies are none, basic, and eager.
This sub-task allows to set this property at the column family level at table
creation time:
{code}
create ‘<tablename>’,
{NAME => ‘<cfname>’,
IN_MEMORY_COMPACTION => ‘<NONE|BASIC|EAGER>’}
{code}
or to set this at the global configuration level by setting the property in
abase-site.xml, with BASIC being the default value:
{code}
<property>
<name>hbase.hregion.compacting.memstore.type</name>
<value><NONE|BASIC|EAGER></value>
</property>
{code}
The values used in this property can change as memstore compaction policies
evolve over time.
