Subject [jira] [Created] (HBASE-12897) Minimum memstore size is a percentage
Date Wed, 21 Jan 2015 21:08:36 GMT
churro morales created HBASE-12897:

             Summary: Minimum memstore size is a percentage
                 Key: HBASE-12897
                 URL: https://issues.apache.org/jira/browse/HBASE-12897
             Project: HBase
          Issue Type: Bug
    Affects Versions: 2.0.0, 0.98.10, 1.1.0
            Reporter: churro morales
            Assignee: churro morales

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?
