Subject [jira] [Commented] (HBASE-17343) Make Compacting Memstore default in 2.0 with BASIC as the default type
Date Sun, 30 Apr 2017 12:19:04 GMT

    [ https://issues.apache.org/jira/browse/HBASE-17343?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15990208#comment-15990208

Anastasia Braginsky commented on HBASE-17343:

Based on the email that [~anoop.hbase] has sent recently the default change is acceptable.
The email is copy-pasted below. We assume the senior committer ([~stack]?) will notify the
community. Thanks everyone for the long and hard work! I am going to commit tomorrow.

bq. Hi All
bq.            Tests are done.. Even with CMS algo also.  As some of our big customers still
use it in production,  I thought will test that also once..  Till now it looks good.. No where
we perform bad compared to default memstore.  (None of my tests do in memory merge btw. Only
it does flattening)

bq. BTW one Q Stack..  Am not sure how many of dev/user track the jira and comments.  Should
we send a notice to dev@/user@ before changing the default type of memstore?
