> 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.
