ryan rawson commented on HBASE-1826:
------------------------------------

I added this because i was testing performance of hdfs-200 with less replication factor to make it faster. It didn't end up working out well, so I more or less dropped it.  I'm not sure its a feature we need exactly.

As for making it a CF attribute, that isn't gonna work because of the 1 hlog per RS covering multiple tables.

> the replication level affects sync performance, so being able to tweak the r= level for HLog only can help.
