-------------------------------------------
Summary: add RangeIterator interface and QueryPlan for SI
Key: CASSANDRA-10765
URL: https://issues.apache.org/jira/browse/CASSANDRA-10765
Project: Cassandra
Issue Type: Sub-task
Components: Local Write-Read Paths
Reporter: Pavel Yaskevich
Assignee: Pavel Yaskevich
Fix For: 3.2
Currently built-in indexes have only one way of handling intersections/unions:
pick the highest selectivity predicate and filter on other index expressions.
This is not always the most efficient approach. Dynamic query planning based on
the different index characteristics would be more optimal. Query Plan should be
able to choose how to do intersections, unions based on the metadata provided
by indexes (returned by RangeIterator) and RangeIterator would became a base
for cross index interactions and should have information such as min/max token,
estimate number of wrapped tokens etc.
