Subject [jira] [Commented] (CASSANDRA-7396) Allow selecting Map key, List index
Date Mon, 18 Apr 2016 14:00:32 GMT


Sylvain Lebresne commented on CASSANDRA-7396:

My preference would be to add nothing more to lists, so no single element selection either.
Again, because the performance of it will be surprising (as we can't optimize it at all) and
lists performance is surprising enough as it is. Of course, if others are strongly _for_ single
element selection on lists, I'd certainly prefer that and no slices than adding both.
