Subject [GitHub] accumulo issue #168: ACCUMULO-4501 (work in progress) Very simple implementa...

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.
