Subject [jira] [Commented] (HBASE-2214) Do HBASE-1996 -- setting size to return in scan rather than count of rows -- properly
Date Thu, 09 Aug 2012 05:36:19 GMT

    [ https://issues.apache.org/jira/browse/HBASE-2214?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13431583#comment-13431583
] 

Lars Hofhansl commented on HBASE-2214:
--------------------------------------

Actually in order to make this work, we'd have make sure an older server can read the Scan
object from newer client, so we cannot do this (since an old servers are deployed already).

If there is no way to do this without changing the version of the Scan version I suggest we
defer this until 0.96.

> 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.
