Sylvain Lebresne commented on CASSANDRA-6477: --------------------------------------------- bq. IMO this should be the default, and WITH {{DENORMALIZED (...)}} syntax could optionally restrict it. If you mean that {{CREATE GLOBAL INDEX on foo(bar)}} would be equivalent to denormalizing everything, then I might prefer being careful in the sense that we may (emphasis on "may") want this to later mean to create the global index as a true index, without anything denormalized. So my suggestion would be simply plainly reject a {{CREATE GLOBAL INDEX}} that doesn't have a {{DENORMALIZED}} clause (so no default in a way). Though I would agree that {{DENORMALIZED *}} should be there as it's probably what we want to recommend as de-facto default. > Global indexes > -------------- > > Key: CASSANDRA-6477 > URL: https://issues.apache.org/jira/browse/CASSANDRA-6477 > Project: Cassandra > Issue Type: New Feature > Components: API, Core > Reporter: Jonathan Ellis > Assignee: Carl Yeksigian > Labels: cql > Fix For: 3.0 > > > Local indexes are suitable for low-cardinality data, where spreading the > index across the cluster is a Good Thing.
