    Description

      As has been raised on numerous occasions, we currently perform no "bitrot" detection on uncompressed data file reads. Currently we serialize an incremental checksum, but this is placed in a separate file, and covers a 64K region. Both of these are undesirable characteristics.

      Ideally following on from CASSANDRA-10153 (or perhaps as part thereof), we should somewhat unify the read paths of uncompressed and compressed data with regard to checksums.
