Benedict commented on CASSANDRA-8707:
-------------------------------------
I've pushed an update to the repository with numerous fixes to the test cases
suppressing all leak detection (except in RefCountedTest, where they're
intended). In doing so I came across several meaningful memory leaks that I've
also fixed. The worst offender being the bloom filter from SSTableWriter, which
was not being freed. Users performing bulk transformations could have
presumably been badly affected by this.
> 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.
