Services Used

AWS Lambda

• runPokemonGoEventPipeline: This function contains the entire Python backend logic. It is triggered by an EventBridge rule to run on a daily schedule.
  • Runtime: Python
  • Timeout: 5 minutes
  • Environment Variables: OPENAI_API_KEY
• getPokemonGoEvents: This function serves as the backend for the API. It queries the PokemonGoEvents DynamoDB table and returns a list of upcoming events.
  • Runtime: Python

Amazon DynamoDB

• PokemonGoEvents: This table stores the structured event data.
  • Primary Key: event_id
  • GSI: UpcomingEventsIndex for querying future events.
  • TTL: Enabled to automatically delete past events.
• ProcessedContentHashes: A simple key-value store to track the hashes of scraped content to prevent redundant processing.

Amazon API Gateway

• /events (GET): An API endpoint that triggers the getPokemonGoEvents Lambda function.
  • CORS: Enabled to allow requests from the mobile app.

Amazon EventBridge

• A scheduled rule is configured to trigger the runPokemonGoEventPipeline Lambda function once a day, ensuring the event data is kept up-to-date.
