Description

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
