currently I am using HUGEINT to store data and using UDF I perform bitwise AND on them. I want to store my data in BLOB and perform same actions, but in data mapping table https://www.monetdb.org/wiki/MonetDB_type_system, I was not able to find BLOB mapping for C and MAL. So: 

1) What are C and MAL mappings for UDF, if they exist?

2) Is it possible to perform Bitwise AND on blob?
