Tonic Structural release notes

MongoDB and Document View: You can use path expressions to protect unscanned fields. If a path expression generator applies to an unscanned field, data generation does not fail and the generator is used to mask the field value.

To use this feature for MongoDB, set the environment setting TONIC_MONGO_DISABLE_FIELD_PROJECTION to true. Otherwise, unscanned fields are skipped automatically during data generation. Note that when this setting is true, any unscanned field that is not protected by a path expression generator causes data generation to fail.
