Subject How scalable are automatic secondary indexes in Cassandra 0.7?
Date Wed, 23 Feb 2011 00:45:40 GMT
Hi, As far as I understand automatic secondary indexes are generated for
node local data.

In this case query by secondary index involve all nodes storing part of
column family to get results (?) so (if i am right) if data is spread across
50 nodes then 50 nodes are involved in single query?

How far can this scale? Is this more scalable than manual secondary indexes
(inverted index column family)? Few nodes or hundred nodes?
