Redis Analysis - Part 2: Simplicity

Redis, initially designed as a simple store, has been criticized for its unreliability and difficulty to manage in production. While some problems may not appear with smaller workloads, issues arise when managing larger instances. The simplicity of Redis's APIs does not always translate into a solid foundation, leading to challenges such as memory management, eviction policies, and persistence. Despite these concerns, the engineering community still demands a simple, low-latency Redis-like API that complements relational databases. A new design for an in-memory database is being developed with the aim of redefining simplicity and ease of use in this domain.
