Stu Hood updated CASSANDRA-1472:
--------------------------------
Attachment: 1472-v5.tgz
Attaching v5, which continues migrating secondary index support into the
db.secindex package in *0016* and *0017*, and adds support for adding and
removing KEYS_BITMAP indexes in *0014*-*0018*.
Adding a bitmap index is accomplished via a new SSTable.clone method (which
makes a hardlinked copy of an SSTable with a new generation number) and
improvements to SSTableWriter.Builder to allow for conditionally writing
components.
TODOs (repeated from previous comments) to be tackled post-merge:
* Better bin selection
* Replace memtable filtering with in-memory index
* Implement OrBiC projection
This is 100% ready for review now.

> 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).
