A bi-directional, persisted KV store that is faster than Redis
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…

In plain words
This is a key-value store designed for applications requiring both speed and data persistence. It targets developers building real-time systems who need faster performance than Redis without sacrificing disk storage. It distinguishes itself through a custom-optimized filesystem, smart write batching, and predictive read fetching. The store supports atomic operations, JSON patching, range scans, and a WebSocket-based pub-sub system that lets front-end applications receive key-change notifications directly without backend relay infrastructure.

We're thrilled to unveil EloqKV, a lightning-fast distributed key-value store with a Redis-compatible API. Built on a new database architecture called the Data Substrate, EloqKV brings significant innovations to database design. Here’s the unique features that makes it stand out: - Flexible Deployment: Run it as a single-node in-memory KV cache, a larger-than-memory database or scale to a highly available, distributed transactional database with ease. - High Performance: Achieves performance levels comparable to top in-memory databases like Redis and DragonflyDB, while significantly…
