Critical Sizing Variables

The critical variables for sizing Teradata Database tables and indexes are the following:

  • Row size
  • Estimated cardinality
  • Presence of fallback
  • Table headers are a fixed variable, but must be considered when you are evaluating the projected sizes of your tables. Ensure that you take multi-value compression into account when sizing table headers (see “Compression Types Supported by Teradata Database” on page 695).
