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).
