Subject Avoiding the system IO cache for compaction
Date Wed, 03 Aug 2011 04:24:07 GMT
Cassandra 'compacts' the way Lucene 'merges' segments.  One
interesting new feature built into Lucene is [1] which avoids loading
the source files into the system IO cache on compaction / merge.

Perhaps Cassandra already has this feature?
