+"""
+Publish events from a CSV to the Event Bus.
+
+This is meant to help republish failed events. The CSV may be an export from Splunk, or it may be manually created, as
+long as it has 'initial_topic', 'event_type', 'event_data_as_json', 'event_key_field', and 'event_metadata_as_json'
+columns.
+
+If the CSV is manually created, you will need to use the python __repr__ of all fields. For strings, including
+json dumps, this means enclosing them in single quotes
+
+Example row (second line split up for readability, in the csv it should be all one line)
+initial_topic,event_type,event_data_as_json,event_key_field,event_metadata_as_json
+'test-topic','org.openedx.test.event','{"user_data": {"id": 1, "is_active": True}}','user_data.id',
+'{"event_type": "org.openedx.test.event", "id": "12345", "minorversion": 0, "source": "openedx/cms/web",
+ "sourcehost": "ip-10-3-16-25", "time": "2023-08-10T17:15:38.549331+00:00", "sourcelib": [8, 5, 0]}'
+
+This is created as a script instead of a management command because it's meant to be used as a one-off and not to
+require pip installing this package into anything else to run. However, since edx-event-bus-kafka does expect certain
+settings, the script must be run in an environment with DJANGO_SETTINGS_MODULE.
+
+To run:
+tox -e scripts -- python edx_arch_experiments/scripts/republish_failed_events.py
+ --filename /Users/rgraber/oneoffs/failed_events.csv
