Branimir Lambov commented on CASSANDRA-11960:
---------------------------------------------
Is it possible to save both the file offset (from {{getSourcePosition}}) as
well as the buffer offset? This would let us resume from exactly where we
stopped, wouldn't it?
I believe the reason I removed the seeking was because I saw it can't work
correctly for compressed files (as we store uncompressed offset but don't have
a way to map it to compressed chunk and offset), and after that I wasn't very
thorough in checking that it's not actually used.
