Subject [jira] [Commented] (HBASE-12897) Minimum memstore size is a percentage
Date Fri, 06 Feb 2015 00:06:35 GMT

Lars Hofhansl commented on HBASE-12897:
---------------------------------------

I meant something different: Remove any minimum size restriction other than saying the cache
size cannot be 0.

> 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?
> What do you folks think?
