Configuring Windows

Use the Window configuration wizard to define a Window in which data is validated in your Source.

To configure a window,

  1. On the Source you want to configure a window for, navigate to the Windows tab.
  2. Click + New window.
  3. Select the Window type that you want to create: Fixed Batch, Global, Tumbling, or File.

📘

Note

File Windows are only supported for Object storage Source types.

  1. Under Config, specify the required config options for your Window type.

📘

Note

When configuring windows, a time field is used. The format of the time field is converted to UTC in Validio, but the graphs will always display times in your system's timezone.

4.1 Fixed batch window

FieldValueDescription
Data-time fieldField nameIdentifier for the index field used to configure the Window.
Batch sizeNumericNumber of datapoints (rows) of the Window. For example, 256.
Segmented batchingTrue
False
If True, each segment gets a separate Window of batch size length.

4.2 Global window--Global window requires no configuration.

4.3 Tumbling window

FieldValuesDescription
Data-time fieldField nameThe name of the field that references the timestamp associated with each record or row in the data source.
Window sizeNumericLength of the Window in the selected time unit. For example, 1
UnitMinute
Hour
Day
Week
Month
Unit of time to define Window size.
Disable window timeoutTrue
False
Set to true if the window should be automatically closed without considering the most recent data-time.

4.4 File window

FieldValueDescription
Data-time fieldField nameIdentifier for the field used to configure the Window.

Note

File window datasets in distribution shift validation--File window datasets are often used in ML use cases to monitor data drifts.

If you use a production training dataset as reference dataset, as new data is collected, you can monitor distribution shift metrics between the reference dataset and the newly collected dataset.

For information on numeric reference metrics, such as relative entropy, refer to the Numeric distribution or Categorical distribution Validator types.

  1. Create validators

Use the Validator configuration wizard to create Validators with your configured Window.
