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.
