Tyler Hobbs commented on CASSANDRA-7563:
----------------------------------------
bq. Will try to improve readability of all tests in UFTest - some support in
CQLTester would be nice - especially after CASSANDRA-7813.
Yes, feel free to add some utility functions, options, etc to CQLTester if
those would make the tests clearer.
bq. isn't that problem a bit more complex? UDFs can get parameters from CQL
statements as 'constants', from CQL bound variables (I think these depend on
the protocol version) and from tables (guess these are always
ProtocolVersion.NEWEST_SUPPORTED).
Literals/constants will end up as Lists.Value, Sets.Value, etc. In the Value
classes, {{getWithProtocolVersion()}} will use the current connection's
protocol version to serialize the list as a ByteBuffer. Somthing similar
happens for bound variables.
When we fetch them from tables, they get serialized based on the current
connection's protocol version _before_ functions are applied. So the function
needs to deserialize them using the same protocol version.

> * is Java Driver as a dependency required ?
> * is it possible to extract parts of the Java Driver for UDT/TT/coll support ?
> * CQL {{DROP TYPE}} must check UDFs
> * must check keyspace access permissions (if those exist)
