Subject [jira] Commented: (CASSANDRA-749) Secondary indices for column families
Date Wed, 03 Feb 2010 20:59:28 GMT


Jonathan Ellis commented on CASSANDRA-749:

I think having each node index its CFs locally is a lose for us, because as you say we have
to query the full cluster for any index lookup, since we are throwing away our usual partitioning

This means we add a ton of complexity (adding a completely different query path) in exchange
for not being able to scale these queries, since the work generated increases in lockstep
w/ machines added.
