Benedict commented on CASSANDRA-8707:
-------------------------------------
Special casing is where many of our recent bugs have come from, as far as I can
tell. They interplay with each other in ways we cannot easily predict,
especially when focusing on one area of the codebase. We think "it'll be fine
here, as it doesn't touch anything else, and I've got a handle on what it does"
- then we remember validation compaction in LCS that breaks our assumption, for
instance.
> Move SegmentedFile, IndexSummary and BloomFilter to utilising RefCounted

> There are still a few bugs with resource management, especially around
> SSTableReader cleanup, esp. when intermixing with compaction. This migration
> should help. We can simultaneously "simplify" the logic in SSTableReader to
> not track the replacement chain, only to take a new reference to each of the
> underlying resources.
