So I looked at the code and the compaction seems to concentrate / find
"most interesting" the newer buckets for compaction.
Our problem is that we have a huge fragmented number of sstables in buckets
that are a few days old. (not yet expired, our expiration is 7 days), so
the sstable selection
We are running Cassandra: 2.1.15, We started noticing below errors, app is
writing larger mutations and before we take a route of increasing from 32MB to
64MB for `commitlog_segment_size_in_mb` wanted to understand if there are any
cons by increasing it. Do we need to tweak any other parameters
