Subject [jira] [Commented] (PHOENIX-2095) Lower the default for phoenix.sequence.saltBuckets
Date Wed, 01 Jul 2015 22:49:04 GMT

    [ https://issues.apache.org/jira/browse/PHOENIX-2095?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14611121#comment-14611121

Andrew Purtell commented on PHOENIX-2095:
-----------------------------------------

By "too many regions" I don't mean it overloads the region carrying capacity or anything like
that. I mean for systems under test all of the SYSTEM.SEQUENCE regions get in the way: in
the UI table view, in copious amounts of INFO and DEBUG level logging, the shell's status
command output, etc.

> 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.
