> we should:
> - use the statistics from CASSANDRA-1155 to figure out which index has the
> highest selectivity, and start with that
> - if other indexes have high selectivity (average number of columns in an
> index row is less than 1% of total in that CF), we should do a merge join
> - otherwise, just loop the results from the first and reject un-satisfied
> expressions
