Subject [jira] [Commented] (HBASE-12897) Minimum memstore size is a percentage
Date Wed, 21 Jan 2015 22:03:35 GMT

Nick Dimiduk commented on HBASE-12897:

+1 to Andrew's suggestion, was going to say the same. How about updating the same checks around
BlockCache? Those checks are from the days of 6-8G heap.

> We have a cluster which is optimized for random reads.  Thus we have a large block cache
and a small memstore.  Currently our heap is 20GB and we wanted to configure the memstore
to take 4% or 800MB.  Right now the minimum memstore size is 5%.  What do you guys think about
reducing the minimum size to 1%?  Suppose we log a warning if the memstore is below 5% but
allow it?
