Blake Eggleston updated CASSANDRA-20373:
----------------------------------------
Description:
The tracked read path currently has no short read protection support, so we can
erroneously return responses under the limit. Short read support needs to be
adapted to work with the logged read classes.
The short read protection dtest is parameterized for replica types, but is only
testing untracked reads, so that is a good place to start. Some of the short
read tests already pass with logged reads due to the way that read response
augmentation works, but things like complementary deletes do not.

The short read protection dtest is parameterized for replica types, but is only
testing legacy reads, so that is a good place to start. Some of the short read
tests already pass with logged reads due to the way that read response
augmentation works, but things like complementary deletes do not.
