[jira] Created: (HBASE-2214) Do hbase-1966 -- setting size to
return in scan rather than count of rows -- properly
Do hbase-1966 -- setting size to return in scan rather than count of rows -- properly
-------------------------------------------------------------------------------------
Key: HBASE-2214
URL: https://issues.apache.org/jira/browse/HBASE-2214
Project: Hadoop HBase
Issue Type: Bug
Reporter: stack
Fix For: 0.21.0
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.

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.
