The discussed key-value store claims to be 2-6 times faster than Redis while ensuring disk persistence. However, the closed source nature of the product has drawn skepticism, particularly from open-source advocates who prefer self-hosted alternatives. Key concerns raised include the legitimacy of the performance claims based on benchmark methods, especially in comparison to single-threaded Redis instances. Comments also highlight the need for clarity on the persistence mechanism, durability guarantees, and whether the system can genuinely provide ACID transactions. The performance claims could be heavily influenced by multi-threading capabilities, attracting further scrutiny from potential users.
