Jeremy Hanna reassigned CASSANDRA-9969:
---------------------------------------
Assignee: Jeremy Hanna
> Expose the DTCS configuration parameters (base time, min threshold, max age)
> via jmx
> ------------------------------------------------------------------------------------
>
> Key: CASSANDRA-9969
> URL: https://issues.apache.org/jira/browse/CASSANDRA-9969
> Project: Cassandra
> Issue Type: Improvement
> Reporter: Jeremy Hanna
> Assignee: Jeremy Hanna
> Labels: compaction, dtcs
>
> The DateTieredCompactionStrategy settings aren't exposed via JMX. There are
> a few use cases for which this would be valuable.
> 1. Testing via write survey mode. Currently you can change the compaction
> strategy class but are limited to change min/max compaction threshold.
> 2. Testing via trying out the strategy on one node in your existing cluster.
> This helps you to understand the impact when transitioning from another
> compaction strategy to DTCS.
> 3. Transitioning your cluster to DTCS one node at a time for minimal impact
> (then of course changing the persisted schema).
> This should go back to 2.0 or at least 2.1 because it's really a simple
> oversight to not have exposed those in ColumnFamilyStoreMBean.
