Subject [jira] [Commented] (HBASE-7803) Look into REST API performance
Date Wed, 13 Feb 2013 00:37:12 GMT

    [ https://issues.apache.org/jira/browse/HBASE-7803?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13577222#comment-13577222

Andrew Purtell commented on HBASE-7803:

bq. do we know why we setCacheBlocks to false all the time in ScannerResultGenerator

REST doesn't know if it should add cache pressure to the RS block cache or not.

bq. we never setCaching to the Scan object in ScannerResultGenerator

Maybe a bug now, something that hasn't been examined I think since ~0.90. If you change this
does this improve the results in your tests?

> I have a YCSB client using the REST API.  My testing shows the performance for scan with
REST API is much worse than that with the java client API.  We need to look into it and find
out the root cause, either the test issue, or our REST API issue.
