T Jake Luciani commented on CASSANDRA-1472:
-------------------------------------------
This might be off topic a bit but was wondering if you had thought about using
Lucene indexes Stu?
1. You would get the lucene search api
2. You could keep a single index per CF and let lucene manage the segment file
management.
3. index.optimize() could be run along size compaction
4. while a SSTable was in the memtable form we could rely on a RamDirectory
then merge with the on disk index after SSTable flush.
The tricky part would be turing the validators into Analyzers I think...

> 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).
