I think the keycaches and rowcahches are bothe persisted to disk when shutdown, and restored from disk when restart, then improve the performance.

主题: keycache persisted to disk ?


I am testing Cassandra on Amazon and finding performance can vary fairly wildly. I'm leaning towards it being an artifact of the AWS I/O system but have one other possibility.

Are keycaches persisted to disk and restored on a clean shutdown and restart ?
