Looks like only SSTableReader calls IndexSummary#getKeys Yes, although some uses, like the one in {{getKeySamples(Range)}}, are going to be tricky without an actual list of keys to work with. > 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 > Fix For: 1.2 > > Attachments: CASSANDRA-4324.patch, CASSANDRA-4324.patch, CASSANDRA-4324.patch, lucene-core-4.0-SNAPSHOT.jar > > > 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 -- This message is automatically generated by JIRA.
