--------------------------------------
Summary: Use direct i/o for sequential operations
(compaction/streaming)
Key: CASSANDRA-7404
URL: https://issues.apache.org/jira/browse/CASSANDRA-7404
Project: Cassandra
Issue Type: Improvement
Components: Core
Reporter: Jason Brown
Assignee: Jason Brown
Fix For: 3.0
Investigate using linux's direct i/o for operations where we read sequentially
through a file (repair and bootstrap streaming, compaction reads, and so on).
Direct i/o does not go through the kernel page page, so it should leave the hot
cache pages unaffected.
