Aleksey Yeschenko resolved CASSANDRA-9969. ------------------------------------------ Resolution: Duplicate Closing as a duplicate of CASSANDRA-9965, which should allow setting compaction options together with the class. > 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. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
