Subject [jira] Commented: (HBASE-2214) Do hbase-1966 -- setting size to return in scan rather than count of rows -- properly
Date Thu, 11 Feb 2010 22:46:28 GMT

    [ https://issues.apache.org/jira/browse/HBASE-2214?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12832716#action_12832716
] 

Kay Kay commented on HBASE-2214:
--------------------------------

Makes sense conceptually . Would be nice to have a final version of the patch logging the
number of rows on the server side when scanning by size , so as to estimate the density /
sparsity of the data across columns when we scan by size.

> The notion that you set size rather than row count specifying how many rows a scanner
should return in each cycle was raised over in hbase-1966.  Its a good one making hbase "regular"
though the data under it may vary.  HBase-1966 was committed but the patch was constrained
by the fact that it needed to not change RPC interface.  This issue is about doing hbase-1966
for 0.21 in a clean, unconstrained way.
