Space-RF builds low-jitter databases and messaging for the hardest real-time envelopes — from fanless single-board computers on a mast to DPDK/SPDK line-rate servers in a hardened rack. Kernel-bypass where it matters. Hard bounds where it counts.
Each ships with formally-modeled invariants, PREEMPT_RT tuning presets, and per-core latency reports. No mystery meat, no "best effort."
In-process, append-structured store with bounded WAL flush, lock-free readers, and a scheduler-aware commit path. From a 512 MB CM5 node to a NUMA-pinned SPDK box — the same API, the same invariants.
Zero-copy pub/sub with pluggable transports — shared memory, DPDK userspace, kernel bypass over 25/100G, or HF/UHF radio on constrained links. Deadline-aware delivery, not just "eventually."
Rack-class OLTP + OLAP on a single engine — when the mission log has to answer both "commit this event now" and "scan the last six hours" on the same data. Kernel-bypass end to end: SPDK for NVMe, DPDK for ingest, no syscalls on the hot path. Extends DB25 research — SIMD-vectorized SQL, lock-free readers, zero-copy execution.
We compile for your actual rig — not a datacenter abstraction. Pick the envelope; the invariants travel with it.
Every figure below comes with the perf script that produced it, the kernel config, and the hardware SKU. No asterisks.
We build as if every commit is landing on a ship, a drone, or a vehicle that cannot be patched for six months. Because most of them are.
Core protocols — consensus, WAL, slot scheduling — are machine-checked before a line of C ships.
Every hot path has a documented worst-case execution time. Regressions break CI.

Space-RF was founded by Chiradip Mandal after leaving Apple, and built alongside the systems it now powers — satellite ground stations, autonomous surface vessels, and mil-grade maritime HF networks. Every spec on this page was earned on customer hardware, under deadlines that did not move.
If a dropped packet, a 50 ms GC pause, or a schedulable drift of a microsecond changes the outcome of a mission — we should talk. If not, we are probably not the right tool.
