Mikhail Bautin updated HBASE-4683: ---------------------------------- Summary: Always cache index blocks (was: Create config option to only cache index blocks) > Always cache index blocks > ------------------------- > > Key: HBASE-4683 > URL: https://issues.apache.org/jira/browse/HBASE-4683 > Project: HBase > Issue Type: New Feature > Reporter: Lars Hofhansl > Assignee: Lars Hofhansl > Priority: Minor > Fix For: 0.94.0 > > Attachments: 4683-v2.txt, 4683.txt > > > This would add a new boolean config option: hfile.block.cache.datablocks > Default would be true. > Setting this to false allows HBase in a mode where only index blocks are > cached, which is useful for analytical scenarios where a useful working set > of the data cannot be expected to fit into the (aggregate) cache. > This is the equivalent of setting cacheBlocks to false on all scans > (including scans on behalf of gets). > I would like to get a general feeling about what folks think about this. > The change itself would be simple. -- This message is automatically generated by JIRA.
