Benedict commented on CASSANDRA-8707:
-------------------------------------
bq. As I said, I'll walk over the code properly and explain the parts I
struggled with.
Thanks. I do want the code to be clear, and would also like to contribute to
that where I am able, so if there are specific things you think I can elaborate
on better, please do point me to them and leave it to me.
Like you say, the code is made up of a lot of individually obvious things, that
aren't obvious as a whole, and I've been lost in the weeds long enough to not
be able to tell the difference between the two.

> 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.
