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. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
