Benedict commented on CASSANDRA-14482:
--------------------------------------
I don't see any issue with doing our own checksumming? It's not like they'll
be doing anything magical. In fact, according to
[this|https://facebook.github.io/zstd/zstd_manual.html] they're just using the
lower 32bits of xxhash64, which we already utilise elsewhere I think? There's
also a good case to made for permitting the checksum to be configurable, so
that the user can decide on their preferred level of protection, both in
algorithm and number of bits.
