Redis is an impressive piece of engineering, but it performs best as an in-memory kv-store on a single core. Its distributed capabilities target a different problem than other distributed kv-stores attempt to solve. Redis Cluster focuses on reasonable functionality for an in-memory store. However, Redis Cluster is neither highly available, nor consistent. There are multiple modes that can cause catastrophic data loss, so Redis Cluster works best in situations where losing data isn't a big deal. For it's intended use case, nothing else comes close to offering the same functionality, performance, reliability, and ease of use.
