[jira] [Created] (CASSANDRA-10154) Uncompressed data files should serialize inline checksums, over smaller blocks

Benedict created CASSANDRA-10154:
------------------------------------

             Summary: Uncompressed data files should serialize inline checksums, over smaller blocks
                 Key: CASSANDRA-10154
                 URL: https://issues.apache.org/jira/browse/CASSANDRA-10154
             Project: Cassandra
          Issue Type: Improvement
          Components: Core
            Reporter: Benedict
             Fix For: 3.x


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.
