Eshcar Hillel created HBASE-17294:
-------------------------------------

             Summary: External Configuration for Memory Compaction=20
                 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 tab=
le creation time:
{code}
create =E2=80=98<tablename>=E2=80=99,
   {NAME =3D> =E2=80=98<cfname>=E2=80=99,=20
    IN_MEMORY_COMPACTION =3D> =E2=80=98<NONE|BASIC|EAGER>=E2=80=99}
{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>
=09<name>hbase.hregion.compacting.memstore.type</name>
=09<value><NONE|BASIC|EAGER></value>
</property>
{code}
The values used in this property can change as memstore compaction policies=
 evolve over time.
