JetstreamDB is a universal filesystem, cache, memory, database. It is a component to build into solutions for management consulting customers. It has been running in production since April 2023. The logo was inspired by the tea clipper. It intends to be a great data store without AI like tea clippers took the seas before ironclads.

It is an open-source component, but we offer paid services with audit, system security reviews, benchmarking, and warranty. Jetstreamdb is available up to 6 TB low latency RAM with optional extra 50 TB SSD configurations for about $150/hr. https://calendly.com/hq-schmied/30min

CactusDB is a high-performance, standalone, and networked in-memory key-value database — built entirely in Rust to deliver systems-level reliability and blazing speed. Designed for developers who demand efficiency without compromise, CactusDB combines the simplicity of an embedded store with the power of a networked database.

At its core, CactusDB features a lock-free DashMap key–value store, enabling ultra-fast read and write operations. It supports TTL and expiry, similar to Redis’ SETEX and EXPIRE, along with atomic increment operations (INCR). To keep memory usage under control, an automatic cleaner task runs in the background, evicting expired keys seamlessly.

The networking layer is built on the Tokio async runtime, offering a fully text-based command protocol inspired by Redis RESP. CactusDB runs a TCP socket server compatible with netcat, telnet, or any TCP client, making it easy to integrate into your existing tooling or scripts. With CactusDB, you get the perfect balance of speed, safety, and simplicity in a modern Rust-powered database.
