Description
we should:
- use the statistics from
CASSANDRA-1155to 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
