●●●BangerWizardryZero to One
TPC-H 1GB in 2 seconds on iPhone—Arrow Flight SQL running locally.
Strengths
- •Full DuckDB server with Arrow Flight protocol on iOS is genuinely novel architecture
- •Verified TPC-H benchmarks show real analytical performance on mobile hardware
- •DuckLake mounting enables actual data lake workflows in your pocket
Weaknesses
- •Enterprise features locked behind commercial license limits open-source utility
- •iOS server use case is niche despite impressive technical achievement

Post Description
Hi, I've created an iOS app (GizmoSQL) for running DuckDB as a server (with Arrow Flight SQL).
You can even mount a DuckLake - meaning you can have a "data lake in your pocket".
It is fully secure, and runs the TPC-H 1GB 22-query benchmark in less than 2 seconds on an iPhone 16 Pro Max.
See: https://github.com/gizmodata/gizmosql for more details...

Rembus – Distributed Messaging (Julia, Python)
Rembus exposes simple node and rpc primitives (expose/rpc) over a tiny brokerable WebSocket transport, so you can spin up remote functions in minutes. The unusual bit is treating a local DuckDB/DuckLake datalake as a first-class part of the runtime, which makes lightweight local analytics painless; I'd still want to see guarantees (delivery semantics, auth, scaling/benchmarking) before trusting it beyond prototypes.
