Andrew Purtell commented on HBASE-14556:
----------------------------------------
Above comment fell victim to spell mangling on the phone. Should read "from a
boolean to an enum..."
> Make prefetchOnOpen configurable for index and/or data blocks

> Key: HBASE-14556
> URL: https://issues.apache.org/jira/browse/HBASE-14556
> Project: HBase
> Issue Type: Bug
> Components: BlockCache, regionserver
> Reporter: Lars George
>
> This came up in user discussions. It would be great to add an extra option to
> the {{CacheConfig}} that allows to specify what blocks are cached during
> region/file opening. This should allows to set {{BlockIndexOnly}},
> {{BloomFilterOnly}}, {{AllIndexesOnly}}, {{DataOnly}}, and {{AllBlocks}}.
> For large datasets it is not viable to load all blocks into memory, but to
> speed up access it still makes sense to prefetch the index blocks (being
> block index and Bloom filter blocks).
