Job Example PTS00029 – Read HDFS and Load into Teradata

Sample Script

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

PTS00029: Read HDFS flat file.

Rationale

This job uses:

  • DataConnector operator template as the producer because it can read files in the HDFS filesystem, referencing values defined in the job variable file without requiring an explicit operator definition.
  • 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.
