Release Note
Description
When writing large amounts of data (e.g during compaction), read latency can be adversely affected if a single sync() is made at the end of writing all the data; as the IO subsystem has a large amount of outstanding writes to flush to disk. By issuing periodic sync() calls the affect on read latency can be signifcantly reduced.
