Subject [jira] [Commented] (HBASE-19282) CellChunkMap Benchmarking and User Interface
Date Sun, 24 Dec 2017 10:58:00 GMT

    [ https://issues.apache.org/jira/browse/HBASE-19282?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16302816#comment-16302816

Anastasia Braginsky commented on HBASE-19282:

Hi All,

Regarding the recent QA failure, the problem is not repeatable on my machine and I cannot
open the Jenkins webUI to see the details.
In a meanwhile, I will rebase and submit another patch.

However, I didn't receive some serious review feedback yet. Cause the target of this change
to be entering both master and release-2.0, I would like to promote this asap.
[~anoop.hbase], [~ram_krish], [~chia7712], [~stack], [~tedyu], and everyone, please take a
moment to look on the patch in RB.

> We have made some experiments how working with CellChunkMap (CCM) influences the performance
when running on-heap and off-heap. Based on those results it is suggested to tie the MSLAB
usage (off-heap or on-heap) with CCM index usage.
