Marcus Eriksson commented on CASSANDRA-8267:
--------------------------------------------
To solve this we need to tell a node whether or not this is an incremental
repair when requesting ranges from it. This breaks streaming message
versioning, meaning we would not be able to stream between two nodes unless
they were both upgraded, which would suck in a minor release.
One "solution" could be to only break streaming for incremental repairs (when
they are initiated on an upgraded node) by adding a new
IncrementalStreamRequest message and failing early if we notice that not all
endpoints included in the incremental repair are upgraded. This would make
old-style repairs still work since they don't use the new message (and full
repairs are the default in 2.1).
WDYT [~yukim]? Would this be acceptable or do you have a better solution? We
kind of have to fix this in 2.1 since it makes incremental repairs quite bad.
