- XXH is significantly faster than both MD5 and SHA-256
- Here we use the 128-bit XXH3
- Keep DIGEST_HASH_SIZE at 16 bytes (same as MD5)
- Reduce COL_DIGEST_SIZE to 32 chars
- Keep DIGEST columns as VARCHAR(32)
Handle string length as size_t, consistently (almost always:))
Change function prototypes to accept size_t, where in the past
ulong or uint were used. change local/member variables to size_t
when appropriate.
This fix excludes rocksdb, spider,spider, sphinx and connect for now.
