Frequently Asked Questions ========================== Can I use Cerberus to validate objects? --------------------------------------- Yes. See `Validating user objects with Cerberus `_. Are Cerberus validators thread-safe, can they be used in different threads? --------------------------------------------------------------------------- The normalization and validation methods of validators make a copy of the provided document and store it as :attr:`~cerberus.Validator.document` property. Because of this it is advised to create a new :class:`~cerberus.Validator` instance for each processed document when used in a multi-threaded context. Alternatively you can use a :class:`py3:threading.Lock` to confirm that only one document processing is running at any given time.
