Manage Validations

When you run a validation on an Expectation, a Checkpoint is added. The Checkpoint saves the Validation Results, runs the Actions you specify, and displays the Validation Results.

To learn more about Validations, see Validator.

Run a Validation on a Data Asset containing partitions

When you connect to a Data Asset, you can add a partition to create Expectations and run validations on subsets of Data Asset records. If you've added a partition, you can run a Validation on the latest Batch of data, or you can select a specific year, year and month, or year, month, and day period for the Validation.

To make the identification of Data Assets containing partitions easier, partition information appears in the Data Asset Overview page and in the Batches & run history pane on the Validations page.
