Vijay commented on CASSANDRA-3648:
----------------------------------
I think we should store the offset, checksum for chunks (buffered chunks in
SequentialWriter) to metadata. While streaming we can just check the checksum
before streaming...
But we might not need checksum over the wire (let TCP handle errors)?
> Repair should validate checksums before streaming
