Estimating the amount of permanent space that a Teradata MultiLoad job requires is a three-step procedure:

  1. Prepare a preliminary estimate for the work table and error table requirements, using a set of simplifying assumptions:
    • There is only one target table.
    • It has no fallback protection, no journals, and no NUSIs.
    • The job does not write to the error tables.
    • The database does not experience a restart condition while the job is running.
  2. Adjust the preliminary estimate according to the actual job requirements and expectations:
    • Fallback protection
    • Journals
    • Non-unique indexes
    • Multiple target tables
    • Error table entries
    • Database restarts
  3. Compute and add the space requirements for the restart log table.

The following topics describe each step of the estimation procedure.
