Extending U-SQL
There are 5 kinds of User-Defined entities in U-SQL
- User-Defined Functions (UDFs)
- User-Defined Types (UDTs)
- User-Defined Aggregators (UDAggs)
- User-defined Operators (UDOs)
- User-Defined Appliers
All of them are defined by .NET code. C# is not required. Any .NET language will work.
