[jira] Updated: (HBASE-1935) Scan in parallel

     [ https://issues.apache.org/jira/browse/HBASE-1935?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

stack updated HBASE-1935:
-------------------------

    Fix Version/s:     (was: 0.20.3)
                   0.21.0

Moving to 0.21.  Lets look at merging this functionality back up into HTable rather than have it in a class of its own.  Also, consider doing this functionality in coprocessors if it makes sense.

> A scanner that rather than scan in series, instead scanned multiple regions in parallell would be more involved but could complete much faster partiularly if results are sparse.
