Github user joshelser commented on the issue: https://github.com/apache/accumulo/pull/168 > One option to consider instead of modifying RFile is to make it a decorator like BloomFilterLayer. BloomFilterLayer stores its information in RFile metadata. I'm think will be problems with this approach, but I would not know what they are w/o actually trying it. This is my first foray into the RFile codebase, so I am very happy to be redirected into a different implementation :). My liberal use of increasing visibility on classes ought to be apparent haha. > Are you considering making this a generic histogram functionality, where the user can configure a function that emits counts for a given Key Value? If we can abstract this specific feature into something more generic without it blowing up, I'm ok with that. I just don't have a big picture view right now.
