> Key: CASSANDRA-7548
> URL: https://issues.apache.org/jira/browse/CASSANDRA-7548
> Project: Cassandra
> Issue Type: Improvement
> Components: Core
> Reporter: Hanson
> Priority: Major
>
> Disk I/O priority: Memtables Flusher shall have higher priority than

> The Compaction shall be able to detect the in-progress of Memtables flushing,
> and slow down itself for disk I/O.
