USE_FILTERS option set to True in settings,
filters will be called once a file object has been verified.
Filters allow post-processing of uploaded files and can be used to extract metadata from file headers and/or generate thumbnail images.
The DataFileObject’s verify method submits a task called “mytardis.apply_filters” to the message broker (RabbitMQ).
This task can be picked up by the “mytardis-filters” microservice: https://github.com/mytardis/mytardis-filters or by your own custom microservice.
