Sample Script

For the sample script that corresponds to this job, see the following script in the sample/userguide directory:

PTS00030: Loading Hadoop Tables Using the TDCH-TPT Interface.


In the first job step, this script uses:

  • DDL operator because it can DROP/CREATE tables prior to loading.

In the second job step, this script uses:

  • DataConnector operator as the producer operator because it can read data from Hadoop tables via the TDCH-TPT interface.
  • Load operator template as the consumer because it is the consumer operator that offers the best performance for high speed writing of a large number of rows into an empty Teradata Database table.
