The known NoSQL vendor has announced the addition of in-memory capabilities to its database offering, sparking concerns about the hybrid approach. Redis, an open-source key-value store with solely in-memory capabilities, has shown that databases like it can significantly improve modern application performance by excelling at latency, throughput, and efficiency. Modern applications require sub-millisecond latency, instant scalability, and efficient data transfer, which in-memory databases like Redis can provide. Attempting to add in-memory capabilities to an incompatible database is doomed to fail, and a best-of-breed approach should be adopted where each component leverages the appropriate database for optimal performance.
