Subject [jira] [Commented] (PHOENIX-2095) Lower the default for phoenix.sequence.saltBuckets
Date Thu, 02 Jul 2015 18:57:04 GMT

    [ https://issues.apache.org/jira/browse/PHOENIX-2095?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14612379#comment-14612379

Nick Dimiduk commented on PHOENIX-2095:
---------------------------------------

I'd prefer to see the cardinality of salting decoupled from region splits. On the other hand,
after HBASE-13103, HBase should just correct itself.

> The current default of phoenix.sequence.saltBuckets is 256 and leads to the creation
of SYSTEM.SEQUENCE with 256 regions (only when first created). This is too many regions for
small test clusters or dev clusters so the default should probably be lowered, with production
sizing documented elsewhere. 
> I suggest a new default of 8, 4, or even 1.
