Gemini types: 'BagType', 'MapType', 'TupleType', 'UDTType' doesn't meet 'gocql.Marshal' requirements

[illia-li]

Scylla can use collection and udt types as primary keys, but gemini cant. Reason: gemini use gocql.Marshal for creating partition keys hash, but 'BagType', 'MapType', 'TupleType', 'UDTType' or/and processing with values of this types doesn't meet the requirements of 'gocql.Marshal'. That`s leads to errors;

Error on get hash for table:pkSet_ck3_col5, values:[0xc00039a040 0xc00039a060 0xc00039a080 0xc00039a0a0]

Error is: marshal: can not marshal non collection type into list
