SDK updates

Polymorphic aggregate functions

User-defined aggregate functions (UDAFs) can now be polymorphic. A polymorphic function can accept any number and type of arguments. For information on how to write a polymorphic function, see Creating a polymorphic UDx.

Complex types in the Python SDK

You can now read and write complex types in user-defined extensions written in Python. The complex types support includes arrays, rows, and combinations of both. For details, see Arguments and return values. For examples of a Python UDx utilizing complex types, see Python example: matrix multiplication and Python example: complex types JSON parser.
