The Teradata ML Engine analytic functions run on the Teradata ML Engine, accessing data that resides on the Teradata SQL Engine.

To run a Teradata ML Engine analytic function, submit a SQL query that references one or more of the Teradata ML Engine functions. The function execution is specified in the FROM clause as a table expression. The exact syntax is specified in Teradata ML Engine Analytic Function Execution SQL Syntax.

These steps performed during function execution:
  1. All required data is transferred from Teradata SQL Engine to Teradata ML Engine using Teradata® QueryGrid™ .
  2. The Teradata ML Engine analytic function is run on the Teradata ML Engine.
  3. Results are returned to Teradata SQL Engine.

    For some analytic functions, additional secondary output tables are also returned to Teradata SQL Engine.

  4. All intermediate data used in executing the Teradata ML Engine analytic function is removed from Teradata ML Engine.
