Redis Cluster for Write Intensive Workloads

When you are working with Redis for your write-intensive workloads, Redis Cluster is your friend. It gives you a built-in way to partition your data across instances to allow you to scale your writes without being bound to how much load a single instance can handle. However, data partitioning is always a challenge and Redis Cluster’s approach is no exception to that. At Deliveroo, we are using Redis Cluster in anger, for handing write intensive workloads (e.g. one use case has 10K writes per seconds, while simultaneously handling 300K reads per seconds). During the time we have been using Redis Cluster, we have gained learnings on how the basics of Redis sharding works, how upfront design choices can have tremendous impact on your performance to how resharding is handled both on the Redis Cluster side as well as through the Redis clients. In this session, I would like to share those invaluable learnings based on our battle-tested, real world experiences. At the end of the session, you should have a far better idea on how you can scale Redis for your write intensive workloads, and what type of surprises might be waiting for you.

I currently work at Deliveroo as a Staff Software Engineer in the Consumer division, working on distributed backend systems which have high throughput, low latency and high availability needs. Before that, I used to work at Redgate as a Technical Lead for 4 years, where I led and line-managed a team of 5 Software Engineers. I was responsible for all aspects of the products delivered by the team from technical architecture to product direction. I was also a Microsoft MVP for 7 years between 2012-2019 on Microsoft development technologies.
