Evaluating performance impact of removing Redis-cache from a Scylla-backed service

This blog post discusses the evaluation of performance issues in a service utilizing Scylla and Redis for caching. The authors detail how the existing cache caused spikes in query performance at the end of 15-minute intervals, leading them to propose and test the removal of Redis caching. Throughout the experiment, they monitored performance metrics, revealing that the removal of Redis did not adversely affect service latency and resulted in an improved utilization of Scylla's native caching capabilities.
