David Alves commented on DRILL-13:
----------------------------------


Julian: I misinterpreted your comment. You're basically saying that we can add 
the bloom filter stuff for the iface later, on some other JIRA.

I guess that is fair enough, although in the case that I'm suggesting the join 
operator gets broken down into two portions one above the SE layer that is 
common to any store that uses bloom filters on one of the joined fields (if the 
bloom filter is kept opaque) and one portion below the SE layer that is 
specific to each SE.

> We're going to need to define a storage engine API.  At a minimum, we'll need 
> to generate a Java one.  We will probably need to also create a CPP one.  
> This task is for the former.  Things that are likely to be included in a the 
> Java interface are: reader (scanner), writer, capabilities interface, schema 
> interface, statistics interface, data layout and ordering
