For three years running, Redis Day Tel Aviv has provided a platform for developers to share their stories about using Redis. This year, an expansion to include Redis Day London is taking place, featuring a diverse lineup of speakers from the community. Speakers will be discussing various topics related to Redis, including its use in high-traffic applications and new features like RESP3 protocol and client-side caching. The event aims to bring together developers, end-users, and contributors to Redis for an informative and engaging experience.
