-----------------------------------------
Summary: Allow configuring max allowable disk usage quota by
keyspace
Key: CASSANDRA-17032
URL: https://issues.apache.org/jira/browse/CASSANDRA-17032
Project: Cassandra
Issue Type: Improvement
Components: Local/Other
Reporter: Josh McKenzie
Assignee: Josh McKenzie
This is a similar idea (basically identical idea; didn't want to steamroll that
old ticket w/an update to description etc) to what was raised and closed in
CASSANDRA-5394. In multi-tenant situations it can be very helpful to provide
disk quotas per Keyspaces for users.
We can do this via a low priority background job that periodically checks disk
usage and flips a bit on the Keyspaces when it's over as well as reverts it
when things settle back down to prevent needing the read-before-write a hard
realtime requirement would introduce. While this would of course allow users to
"burst" their usage past that limit in the time window, it would still be
sufficient for many use-cases.
