Hi, I need to do a secondary index access improvement with a little modification to Cassandra. I could see in [1], that the performance of secondary index querying can be increased via splitting the column family data and secondary index data. Currently Cassandra saves keyspace data and secondary indices data in "var/lib/cassandra/data/". According to my understanding the data saves in the "data_file_directories" location of conf/cassandra.yaml file. If I can enter new variable into "cassandra.yaml" file and address it in the place where Cassandra stores secondary indexes, this can be fixed.
Can anyone give some guidance regarding this improvement. [1] https://issues.apache.org/jira/browse/CASSANDRA-5502 Thanks, Nipuni -- Nipuni Piyabasi Perera Undergraduate Department of Computer Science And Engineering University of Moratuwa Sri Lanka
