Interactive (good for development): Specify the name of the validation operator using the --name argument and the name of the expectation suite using the --suite argument. The cli will help you specify the batch of data that you want to validate interactively. 2. Non-interactive (good for production): Use the `--validation_config_file` argument to specify the path of the validation configuration JSON file.
