Description

Since CASSANDRA-6717 decoupled a secondary index from a single column, we can expand support for indexes with multiple target columns and for row-based indexes with truly dynamic targets.

Much of the plumbing for this has been done in CASSANDRA-7771, CASSANDRA-6717 & by the API rework in CASSANDRA-9459. What remains is:

• Decide on syntax for DDL statements
• Decide on WHERE clause syntax for SELECT (there is some discussion on this in the comments of CASSANDRA-9459)
