C. Scott Andreas updated CASSANDRA-7065:
----------------------------------------
Component/s: Local Write-Read Paths
> 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
> Components: Local Write-Read Paths
> Reporter: Marcus Eriksson
> Priority: Major
> Labels: lcs
>
> 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).
