Michael Semb Wever updated CASSANDRA-18312:
-------------------------------------------
Description:
>From 5.0 sstable formats before {{\-na\-}} are unsupported.
This patch cleans up code related to the older formats.
https://github.com/apache/cassandra/compare/trunk...thelastpickle:cassandra:mck/18312/trunk
Raises the question whether backward compatibility to the previous major is
defined by the Cassandra version or by the internal component version (sstable
format).
Also raises the question on whether downstream forks are wanting to support
such upgrade paths, e.g. offline, and to what versions the {{sstableupgrade}}
tool supports. This also touches on recent discussions around
[Downgradability|https://lists.apache.org/thread/tcp339k5ph8ql35wxr085to4qgp8tpg7].
