> Disk I/O priority control for Compaction and Flusher
> ----------------------------------------------------
>                 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.
