Subject [jira] [Commented] (HBASE-1935) Scan in parallel
Date Fri, 09 Dec 2016 07:52:58 GMT

    [ https://issues.apache.org/jira/browse/HBASE-1935?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15734614#comment-15734614

Xiang Li commented on HBASE-1935:

Hi [~stack], I am quite interested on this, and would like to follow the work based on yours
and Lars(in HBASE-9272) to see if I can do something. I am reading code and comment history
of both JIRAs, and there might be a long list of questions to bother you, thanks you in advance!
I am also reading HBASE-16833 (about async client by Duo Zhang) as I feel I can learn some
ideas of it. 
1 quick question: Could you please share the reason why you stopped at that time?
Please feel free to comment if you have any!

would be more involved but could complete much faster partiularly if results are sparse.
