Subject [jira] [Commented] (HBASE-1225) [performance] Return results on scanner open, not just on next + make close asynchronous and unnecessary if scanner is exhausted
Date Sat, 18 May 2013 20:25:15 GMT

    [ https://issues.apache.org/jira/browse/HBASE-1225?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13661422#comment-13661422
] 

stack commented on HBASE-1225:
------------------------------

As of 0.95 and pb, if server says no more results, then clientside we will set the ClientScanner
as closed and scannerId as -1 (another indicator of closedness).  Client-side, we may subsequently
call close on the scanner and find the closed flag so we'll save on the close rpc we used
do.

Remaining then is returning results as well as the scannerid on scanner open.
