Subject [jira] [Updated] (HBASE-11007) BLOCKCACHE in schema descriptor seems not aptly named
Date Sat, 17 May 2014 21:29:16 GMT

     [ https://issues.apache.org/jira/browse/HBASE-11007?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

stack updated HBASE-11007:
--------------------------

        Fix Version/s: 0.99.0
    Affects Version/s:     (was: 0.94.18)
                       0.94.19
               Status: Patch Available  (was: Open)

Making the patch for trunk.  I could make a patch for 0.94 to backport the javadoc piece (since
it already has a test, a test that is better than what I'm adding to trunk).  You want it

> Hi,
> It seems that setting BLOCKCACHE key to false will disable the Data blocks from being
cached but will continue to cache bloom and index blocks. This same property seems to be called
cacheDataOnRead inside CacheConfig.
> Should this be called CACHE_DATA_ON_READ instead of BLOCKCACHE similar to the other CACHE_DATA_ON_WRITE/CACHE_INDEX_ON_WRITE.
We got quite confused and ended up adding our own property CACHE_DATA_ON_READ - we also added
some unit tests for the same.
> What do folks think about this ?
> Thanks
