I am wondering is there any function that serialize data types in memory-comparable format, similar to MySQL and MariaDB. With that kind of function, we can directly store the serialized format in the storage engine and compare them in the storage engine level instead of deserializing data and comparing in the upper level.
Do you mean a format that can perform Index comparisons using a memcmp() rather than per-datatype comparison code?
