Jean-Daniel Cryans commented on HBASE-6128:
-------------------------------------------
I'm talking about this:
http://docs.guava-libraries.googlecode.com/git/javadoc/com/google/common/cache/CacheBuilder.html#weigher(com.google.common.cache.Weigher)
You could write one that weights each block in terms of how big they are. Not
all blocks are created equal.
> Use weights instead of block counts in DoubleBlockCache with CacheBuilder

> Project: HBase
> Issue Type: Bug
> Reporter: Jean-Daniel Cryans
> Priority: Minor
>
> Thanks to HBASE-5739 we can now specify a max weight instead of a maximum
> number of blocks in the DoubleBlockCache. This will give a more accurate
> control over its memory usage.
