Subject [jira] Updated: (HBASE-783) For single row, single family retrieval, getRow() works half as fast as getScanner().next()
Date Mon, 28 Jul 2008 19:51:31 GMT

     [ https://issues.apache.org/jira/browse/HBASE-783?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Jonathan Gray updated HBASE-783:
--------------------------------

    Description: 
We have a very typical use-case of wanting to retrieve all columns under a single row, single
family.

Benchmarking regularly reproduces the same result.  Using HTable.getScanner().next() to get
the RowResult works twice as fast as HTable.getRow().

This is related to HBASE-631 by jdcryans which added this functionality to getRow().

This is related to HBASE-631 which is an optimization by jdcryans for this exact operation.
