C. Scott Andreas updated CASSANDRA-14499:
    Component/s: Core

> node-level disk quota
> ---------------------
>                 Key: CASSANDRA-14499
>                 URL: https://issues.apache.org/jira/browse/CASSANDRA-14499
>             Project: Cassandra
>          Issue Type: New Feature
>          Components: Configuration, Core
>            Reporter: Jordan West
>            Assignee: Jordan West
>            Priority: Major
> Operators should be able to specify, via YAML, the amount of usable disk 
> space on a node as a percentage of the total available or as an absolute 
> value. If both are specified, the absolute value should take precedence. This 
> allows operators to reserve space available to the database for background 
> tasks -- primarily compaction. When a node reaches its quota, gossip should 
> be disabled to prevent it taking further writes (which would increase the 
> amount of data stored), being involved in reads (which are likely to be more 
> inconsistent over time), or participating in repair (which may increase the 
> amount of space used on the machine). The node re-enables gossip when the 
> amount of data it stores is below the quota.   
> The proposed option differs from {{min_free_space_per_drive_in_mb}}, which 
> reserves some amount of space on each drive that is not usable by the 
> database.
