[jira] [Commented] (HBASE-5381) Make memstore.flush.size as a table level configuration
[ https://issues.apache.org/jira/browse/HBASE-5381?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanelfocusedCommentId=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? Make memstore.flush.size as a table level configuration --- Key: HBASE-5381 URL: https://issues.apache.org/jira/browse/HBASE-5381 Project: HBase Issue Type: Improvement Reporter: Liyin Tang Assignee: Liyin Tang 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. -- This message is automatically generated by JIRA.
