Explore caching strategies in microservice architectures through a live coding demonstration at EuroPython 2023. Delve into the implementation of a cache system that reduces database queries without altering the API client, using a typical setup with an API Gateway and a backend service with its own database. Learn practical solutions to one of programming's notorious challenges: cache invalidation in a distributed environment. Gain insights from this 40-minute conference talk, designed to enhance your understanding of efficient caching techniques in modern software development.
