Pavel Yaskevich commented on CASSANDRA-11110:
---------------------------------------------
[~jbellis] [~beobal] I've spend some time working on this today and it looks
like implementing ALLOW FILTERING "avoidance" for individual restrictions is
going to be pretty straight-forward e.g. simply adding
Index.requiresFiltering(Operator) and
Restriction(s).requiresFiltering(SeconaryIndexManager) might suffice. That
said, it's actually going to be move involved to avoid ALLOW FILTERING across
restrictions e.g. (age > 5 AND first_name = 'Pavel') and would require
CASSANDRA-10765 to be implemented since common interface across indexes and
QueryPlan would be a proper way to determine if different indexes are
intersect-able and in what way, I don't, at the moment, see any other way to
properly do that.
