Subject [jira] [Commented] (CASSANDRA-1472) Add bitmap secondary indexes
Date Fri, 27 May 2011 02:49:48 GMT

Feng commented on CASSANDRA-1472:
---------------------------------

Stu,

Since the bitmap index isn't a good fit for rapidly changing data, is there any plan for implementing
a b-tree index? Currently the lack of range scan for secondary indexes is only thing preventing
me from using this otherwise fantastic product. Thanks.

> Bitmap indexes are a very efficient structure for dealing with immutable data. We can
take advantage of the fact that SSTables are immutable by attaching them directly to SSTables
as a new component (supported by CASSANDRA-1471).
