Kannan Muthukkaruppan updated HBASE-4434: ----------------------------------------- Issue Type: Improvement (was: Bug) Bug -> Improvement > Don't do HFile Scanner next() unless the next KV is needed: > ----------------------------------------------------------- > > Key: HBASE-4434 > URL: https://issues.apache.org/jira/browse/HBASE-4434 > Project: HBase > Issue Type: Improvement > Reporter: Kannan Muthukkaruppan > Assignee: Kannan Muthukkaruppan > > When a seek/reseek is done on StoreFileScanner, in addition to setting the > current KV, it also does a HFileScanner level next() ahead of time even if > the next KV is never actually required. This inefficiency can potentially > result in additional disk seeks and sub-optimal use of the block cache > (primarily for cases where the KVs are large and each occupies an HFile block > of its own). -- This message is automatically generated by JIRA.
