>                 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 Compaction.
> This is to avoid DB Insert/Update hung (spikes) during SSTables Compaction. The Compaction shall be able to detect the in-progress of Memtables flushing, and slow down itself for disk I/O.
