Subject [jira] [Commented] (HBASE-5381) Make memstore.flush.size as a table level configuration
Date Fri, 10 Feb 2012 18:41:00 GMT

    [ https://issues.apache.org/jira/browse/HBASE-5381?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13205617#comment-13205617

Jean-Daniel Cryans commented on HBASE-5381:
-------------------------------------------

It already is, see MEMSTORE_FLUSHSIZE in the shell or HTD.setMemStoreFlushSize(). Am I missing
something?

> Currently the region server will flush mem store of the region based on the limitation
of the global mem store flush size and global low water mark. However, It will cause the hot
tables, which serve more write traffic, to flush too frequently even though the overall mem
store heap usage is quite low. Too frequently flush would also contribute to too many minor
compactions. 
> So if we can make memstore.flush.size as a table level configuration, it would be more
flexible to config different tables with different desired mem store flush size based on compaction
ratio, recovery time and put ops.
