**Schema**

* **data** object required

  * **fieldStatistics** object,null

    When you configure the dataset [fields schema](https://docs.apify.com/platform/actors/development/actor-definition/dataset-schema/validation), we measure the statistics such as `min`, `max`, `nullCount` and `emptyCount` for each field. This property provides statistics for each field from dataset fields schema.\
    \
    See dataset field statistics [documentation](https://docs.apify.com/platform/actors/development/actor-definition/dataset-schema/validation#dataset-field-statistics) for more information.

    * **property name\*** DatasetFieldStatistics

      * **min** number | null nullable

        Minimum value of the field. For numbers, this is calculated directly. For strings, this is the length of the shortest string. For arrays, this is the length of the shortest array. For objects, this is the number of keys in the smallest object.

      * **max** number | null nullable

        Maximum value of the field. For numbers, this is calculated directly. For strings, this is the length of the longest string. For arrays, this is the length of the longest array. For objects, this is the number of keys in the largest object.

      * **nullCount** integer | null nullable

        How many items in the dataset have a null value for this field.

      * **emptyCount** integer | null nullable

        How many items in the dataset are `undefined`, meaning that for example empty string is not considered empty.
