I'd like to suggest a few dependencies that would make it easier to talk to the compose-for-* database offerings on IBM Cloud. Here's what I think we need for Python:

• PostgreSQL psycopg2 http://initd.org/psycopg/
• MySQL (rarely used with Python)
• MongoDB pymongo https://api.mongodb.com/python/current/
• Redis redis-py https://github.com/andymccurdy/redis-py
• RabbitMQ pika https://github.com/pika/pika
• Etcd (no recommended driver)
• ElasticSearch elasticsearch-py https://www.elastic.co/guide/en/elasticsearch/client/python-api/current/index.html
• ScyllaDB cassandra-driver https://datastax.github.io/python-driver/
