Dependency:

• Docker
• Cassandra
  • Modify cassandra.yaml to your host ip
• Kafka
• Faust
• Python
• Tweepy
• Twitter API Key
• CompareCrypto API Key

Start the Pipeline:

1. Start ec2 instance from Redash AMI (t2.xlarge)
2. Start Kafka: docker-compose -f docker-compose-cryptotweetmap.yml up
3. Start Cassandra: ./apache-cassandra-4.0.3/bin/cassandra
4. Start Faust Twitter Worker: python3 tw_worker.py worker -l info
5. Start Faust Coin Worker: python3 coin_worker.py worker -l info --web-port 6067
6. (Optional) Test workers: python3 tw_worker.py send twitter '{"uuid": "cb72dea4-c5fd-11ec-975d-0242ac1c0002", "coin": "ETH", "time": 1651046086.2908614}'
7. (Optional) Test workers: python3 coin_worker.py send coinbase '{"uuid": "cb72dea4-c5fd-11ec-975d-0242ac1c0002", "coin": "BTC", "time": 1651046086.2908614, "quote": 38342.44}'
8. Start collecting twitter data: python3 cryptotweet.py
9. Start collecting quotes: python3 cryptoprice.py
10. Configure Redash: http://your_ec2_public_ip/
