Table Changes That Can Be Tracked

In addition to collecting access counts (which are done once per request), object use counts collect the number of updates, deletes, and inserts performed against database tables involved in the request. This information is useful in calculating table row count estimations, statistics extrapolations, and thresholds for statistics collection.

Teradata Database supports these requests and logs them to the Data Dictionary table DBC.ObjectUsage:

  • Selects
  • Updates
  • Deletes
  • Inserts
  • Merges (including merge, merge-delete, and merge-update)
  • Upserts
  • Statistics access
