Subject [jira] [Commented] (HBASE-8946) Add a new function to Thrift 2 to open scanner, get results and close scanner
Date Fri, 19 Jul 2013 21:30:50 GMT

    [ https://issues.apache.org/jira/browse/HBASE-8946?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13714099#comment-13714099

Lars George commented on HBASE-8946:
------------------------------------

For some reason ThriftHBaseServiceHandler.java is different in 0.95, i.e. it is lacking some
formatting updates. Let me bring them to the same level and commit that as part of the patch.
In other words, never mind about a 0.95 patch, the trunk one will apply.

> We found, very often we open a scanner , get x number of rows , then close the scanner
immediately. The attached patch , add a new function *getScannerResults* that does just that.

> Using getScannerResults function reduce number of calls to thrift server. Also since
the scanner gets closed immediately, it is less prone to cause memory leak.
