Data Quality

Users will be able to check if data in Aurora tables is accurate, consistent, complete, and reliable using Data Quality functionality. Data Quality requires SELECT permission over the tested object.

Comments

Dataedo reads PostgreSQL comments from following objects:

• Tables

  • Columns

• Views

  • Columns

• Functions

Dataedo does not write comments back to PostgreSQL at this moment.

Known Issues

• using encoding different than UTF-8 (unicode) causes errors

• rules are not imported

• trigger functions are grouped with standard functions

• dependencies are imported only from views

• tables and views with no comments, but containing column level comments are not correctly imported. Add a table level comment to solve the issue

Limitations

Following schema elements currently are not supported:

• Check constraints

• Non unique indexes

• Sequences

• User defined types
