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'. > Implement Lucene FST in for key index > ------------------------------------- > > Key: CASSANDRA-4324 > URL: https://issues.apache.org/jira/browse/CASSANDRA-4324 > Project: Cassandra > Issue Type: Improvement > Reporter: Jason Rutherglen > Assignee: Jason Rutherglen > Priority: Minor > Attachments: CASSANDRA-4324.patch > > > The Lucene FST data structure offers a compact and fast system for indexing > Cassandra keys.
