["Yi Liang (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/HBASE-1537?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12845166#action_12845166 ] 

Yi Liang commented on HBASE-1537:
---------------------------------

This feature looks very useful for my ongoing project, but the attached patches here can't be applied to my hbase 0.20.3. There're some unmatched hunks in Scan.java and HRegion.java, especially much difference in nextInternal method of HRegion.java. As a common user of HBase, I'm not clear how to adjust the related code. Can anybody provide a patch for 0.20.3? Thanks very much!

> To continue scaling numbers of columns or versions in a single row, we need a mechanism to scan within a row so we can return some columns at a time.  Currently, an entire row must come back as one piece.
