we've been working on a KV store for the past year or so which is 2-6x faster than Redis (benchmark link below) yet disk persisted! so you get the speed of in-memory KV stores but with disk persistence. To achieve this we've created our custom filesystem that is optimized for our special usecase and we're doing smart batching for writes and predictive fetching for reads.

In addition to basic operations, it also provides atomic inc/dec, atomic json patch, range scans and a unique key monitoring mechanism (pub-sub) over WebSockets which essentially allows you to receive notification on registered key changes directly from the KV store. so for example in a realtime web application, you can receive notifications directly in your front-end, with no back-end implementation (no WebSocket server management, no relay etc.) and still be secure and not expose your API keys on front-end. We have REST, WebSocket and RIOC API and we can't wait to hear your feedback.

We're only providing the free tier for now but let us know and we can increase the limits for you, if have a specific case. please either send us an email to [email protected] or use http://hpkv.io/contact if you prefer that way.
