The Teradata collector can be run in the cloud or on-premise using Docker or Jar files.

Note

The latest version of the Collector is 2.222. To view the release notes for this version and all previous versions, please go here.

Use this collector to harvest metadata from Teradata including user defined functions, stored procedures, triggers, user defined types and user defined methods.

What is cataloged

The collector catalogs the following information.

Note

The collector harvests all versions of overloaded functions and stored procedures. Each version has its own title/name in the catalog, but a distinct identifier.

Relationships between objects

By default, the harvested metadata includes catalog pages for the following resource types. Each catalog page has a relationship to the other related resource types. If the metadata presentation for this data source has been customized with the help of the data.world Solutions team, you may see other resource pages and relationships.

Lineage for Teradata

The following lineage information is collected by the Teradata collector.

Table 4.

Object

Lineage available

View

The collector identifies the associated column in an upstream view or table:

  • Where the data is sourced from

  • That sort the rows via ORDER BY

  • That filter the rows via WHERE/HAVING

  • That aggregate the rows via GROUP BY

Stored procedure

The collector identifies:

  • The associated column in an upstream view or table

    • Where the data is sourced from

    • That sort the rows via ORDER BY

    • That filter the rows via WHERE/HAVING

    • That aggregate the rows via GROUP BY

  • The downstream table that has its tables updated.

NOTE:

  • Lineage is not available when the SQL Statement in Stored Procedures contains the SELECT INTO clause.

  • Stored procedures with multiple insert statements are not supported
