> A little bit about this CF. It stores data with a TTL of up to 30 days. These rows are wide. We run major compactions to remove expired data. This has been our setup for almost 2 years and this issue only started cropping up after upgrading to 1.2.5 (from 1.1.5)
> I've been running scrub in the meantime to remove expired data. Now, I'm ending up with lots of similarly sized SSTables that C* is trying constantly to compact. These minor compactions of the bigger SSTables are failing also.
