> Date Tiered Compaction for time series data at high volume it seems like a good candidate for multi-tiered storage options for cost reduction purposes. 
> For example setting max_sstable_age_days = 1 means that once a file hits 1 day old it won't be a candidate for compaction any longer. For immutable time series data you could in theory then have a new DTCS and yaml setting that says move anything over X days (table def) into the cold storage directory from the yaml file. 
> This way you could have pricer, smaller SSD drives for recent data and cheaper, magnetic storage for longer term data that is infrequently read after a certain period of time. 
> cc [~Bj0rn] for input and feasibility.
