Architecture

reddit_sentiment_analysis_pipeline_architecture

All applications in the above architecture are containerized into Docker containers, which are orchestrated by Kubernetes - and its infrastructure is managed by Terraform. The docker images for each application are available publically in the Docker Hub registry. Further details about each layer is provided below:

  1. Data Ingestion : A containerized Python application called reddit_producer connects to Reddit API using credentials provided in the .config/reddit_producer.cfg file. It takes the received messages (reddit comments) and converts select messages into a JSON format. These transformed messages are then sent and stored in a Kafka broker. PRAW python library is used for interacting with Reddit API.

  2. Message Broker : The Kafka broker (kafkaservice pod), recieves messages from the reddit_producer. The Kafka broker is accompanied by the Kafdrop applicatino, which acts as Kafka mointoring tool through UI. When Kafka starts, another container named kafkainit creates the topic redditcomments. The zookeeper pod is launched before Kafka for managing Kafka metadata.

  3. **Stream Processer : TODO

  4. **Processed Data Storage : TODO

  5. **Data Visualisation : TODO
