Subject [jira] [Commented] (CASSANDRA-10124) Support for multi-column indexes
Date Fri, 18 Sep 2015 07:45:04 GMT


Sylvain Lebresne commented on CASSANDRA-10124:

bq. how about we preserve existing behaviour for single target indexes whilst for anything
else have the generated names be simply of the form table_idx, with the existing numeric suffix
in the case of duplicates?

Yes, that's more or less what I add in mind so I would be good with that.

> 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
> 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)
