algorithmiaio/heroku-kafka-demo

To be used part of Heroku's KAFKA 5-parts demo (https://heroku.github.io/kafka-demo/). This is part #6, which adds sentiment analysis to the data pipeline.

Heroku + KAFKA + Algorithmia

This app is one component of the Algorithmia/Kafka demo. Intended to populate the average sentiment for a topic.

Running

Make sure you define the environment variables (through attachment to your Kafka addon):

• KAFKA_URL: Comma-separated list of Kafka broker URLs
• KAFKA_CLIENT_CERT: Contents of the Kafka client certificate. This is set on a Heroku app when the Apache Kafka on Heroku add-on is attached.
• KAFKA_CLIENT_CERT_KEY: Contents of the Kafka client certificate key. This is set on a Heroku app when the Apache Kafka on Heroku add-on is attached.
• KAFKA_CONSUMER_TOPIC: Kafka topic name from which to consume messages.

Make sure you also have Algorithmia-specific environment variables:

• ALGORITHMIA_API_KEY: your API key, ideally one that you created only for this project

If you're using a private/on-prem version of Algorithmia (CODEX), you'll want to define another environment variable ALGORITHMIA_API_KEY to point to your private cluster. For most users you will not need to bother about this.
