Teradata PT Processor

The Teradata PT processor parses, compiles, and executes a series of statements submitted as a Teradata PT job script.

Functional components of the Teradata PT processor include:

  • An interface for submitting user requests
  • A compiler that validates the Teradata PT job script statements and generates and optimizes an internal operating plan
  • An internal metadata manager
  • A data stream controller that uses parallel launch and interprocess communication facilities for routing data between operators
  • A checkpoint-restart manager that provides recovery functions for a Teradata PT job
