Marcus Eriksson created CASSANDRA-7065: ------------------------------------------
Summary: Add some extra metadata in leveled manifest to be able to reduce the amount of sstables searched on read path Key: CASSANDRA-7065 URL: https://issues.apache.org/jira/browse/CASSANDRA-7065 Project: Cassandra Issue Type: Improvement Reporter: Marcus Eriksson Based on this; http://rocksdb.org/blog/431/indexing-sst-files-for-better-lookup-performance/ By keeping pointers from the sstables in lower to higher levels we could reduce the number of candidates in higher levels, ie, instead of searching all 1000 L3 sstables, we use the information from the L2 search to include less L3 sstables. First we need to figure out if this can beat our IntervalTree approach (and if the win is worth it). -- This message was sent by Atlassian JIRA (v6.2#6252)
