             Summary: Make DateTieredCompactionStrategy easier to use
                 Key: CASSANDRA-9645
                 URL: https://issues.apache.org/jira/browse/CASSANDRA-9645
             Project: Cassandra
          Issue Type: Improvement
            Reporter: Marcus Eriksson


It has proven to be quite difficult to use DTCS properly, we need to make it 
easier and safer. Things to do could be (but there is surely more things) :

* put warnings in logs if read repair is used
* better debug logging which explains why certain sstables are selected etc
* Auto-tune settings, this could be quite difficult, but we should atleast do 
CASSANDRA-9130 to default max_sstable_age to gcgs.
