Jason Rutherglen updated CASSANDRA-4324:
----------------------------------------
Attachment: CASSANDRA-4324.patch
Attached is a rough first cut of this functionality. It is in a rough state
however I figured now is a good point to get some feedback before proceeding
further.
In the dev environment I had to copy the Lucene library into the project and am
not sure why that is necessary, as Lucene is included as a dependency in the
pom.xml file.
The sample key range code is confusing as I am unsure of the purpose.
The patch was created using 'git diff'.

> The Lucene FST data structure offers a compact and fast system for indexing
> Cassandra keys. More keys may be loaded which in turn should seeks faster.
> * Update the IndexSummary class to make use of the Lucene FST, overriding the
> serialization mechanism.
> * Alter SSTableReader to make use of the FST seek mechanism
