------------------------------------------

[~devaraj], please see the performance benchmarks results reported in 
HBASE-16417. We started writing a separate blog post with clearer and more 
concise description. Thanks.

> 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 
> hbase-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.
