Jean-Marc Spaggiari updated HBASE-20105:
----------------------------------------
Release Note:
Introducing hbase.hstore.flush.storagepolicy column family parameter.
public static final String FLUSH_STORAGE_POLICY =
"hbase.hstore.flush.storagepolicy";
This parameters allows the user to target specific storage policy for flushes.
There can be 3 storage policy settings. HBase will use the first configured.
1)
The following table creation command will instruct HBase to re-direct all
memstore flushes into SSD drives:
create 't1', {NAME => 'f1', CONFIGURATION => {'hba
se.hstore.flush.storagepolicy' => 'ALL_SSD'}}

> On heavy writes usecases, flushes are compactes together pretty quickly.
> Allowing flushes to go on SSD allows faster flush and faster first
> compactions. Subsequent compactions going on regular storage.
>
> I will be interesting to have an option to target SSD for flushes.
