Subject [jira] [Updated] (HBASE-6114) CacheControl flags should be tunable per table schema per CF
Date Sun, 27 May 2012 19:09:23 GMT

     [ https://issues.apache.org/jira/browse/HBASE-6114?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Andrew Purtell updated HBASE-6114:
----------------------------------

      Description: 
CacheControl flags should be tunable per table schema per CF, especially
cacheDataOnWrite, also cacheIndexesOnWrite and cacheBloomsOnWrite.

It looks like Store uses CacheConfig(Configuration conf, HColumnDescriptor family) to construct
the CacheConfig, so it's a simple change there to override configuration properties with values
of table schema attributes if present.

  was:
CacheControl flags should be tunable per table schema per CF, especially
hbase.rs.cacheblocksonwrite, also hfile.block.index.cacheonwrite, io.storefile.bloom.cacheonwrite.

It looks like Store uses CacheConfig(Configuration conf, HColumnDescriptor family) to construct
the CacheConfig, so it's a simple change there to override configuration properties with values
of table schema attributes if present.

    Fix Version/s: 0.94.1
                   0.96.0
                   0.92.2
