Subject [jira] [Commented] (HBASE-7630) support large number of small regions
Date Thu, 24 Jan 2013 18:41:14 GMT

    [ https://issues.apache.org/jira/browse/HBASE-7630?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13561841#comment-13561841
] 

Sergey Shelukhin commented on HBASE-7630:
-----------------------------------------

My main goal would be improving compactions (but this can be achieved with certain level-like
compaction algorithm, call it stripe-compactions :)), and improving failover (where there
are many small regions, it's easier to shuffle them and preserve both locality and balance
of data size between servers).
Also good for reads, yes.

> Supporting large number of small regions can help improve scalability in terms of number
of tables/cfs/etc., help speed up recovery, and also lessen the impact of compactions (due
to there being a large number of small compactions). 
> This is an issue to attempt brainstorming current limitations.
> We might want to take this into consideration when designing master tasks such as in
HBASE-5487.
