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

The Teradata PT processor includes the following components and functionality:

  • Interface (for submitting user requests)
  • Compiler (validates the Teradata PT job script statements and generates and optimizes an internal operating plan)
  • Internal metadata manager
  • Data stream controller (uses parallel launch and interprocess communication facilities for routing data between operators)
  • Checkpoint-restart manager (provides recovery functions for a Teradata PT job)
