Preview schemas sample column data - Take a sneak peek at your column data while creating a schema in the schema wizard, or in the table details page of physical or business schemas.
Security New user and group security management UI - Create users, groups, and manage security privileges through the face-lifted security section of the web application.
Dashboards & Insights Create data alerts from the dashboard - Set a data alert for an Insight right from within the dashboard containing that Insight.

  4. When upgrading from 4.0 thru 4.2.x to 4.3, It is important to upgrade the metadata database using the following:

    • Go to the cd <IncortaInstallation>/cmc/tmt/ directory.

Known Issues

Deleting a schema causes Incorta to freeze. You can replicate this error using the following steps:

  1. Create two or more schemas.
  2. Create overlapping scheduled jobs.
  3. Select two schemas to delete, icluding one schema with a scheduled job.

Expected behavior: The schemas are deleted and no exceptions happen.

Actual behavior: The schemas are deleted and Incorta freezes.
