Fast data transport : Apache Arrow, Protobuf and Message Pack data on the one stream. Measured faster than Arrow Flight on all open benchmarks. HTTP, TCP, QUIC, Websocket, Webtransport, Stdio, UDS, all interchangeable, with 64-byte SIMD compatibilty maintained over the network and to/from disk via custom Arrow Mmap and Parquet Readers and Writers

Transport-agnostic RPC framework built on Apache Arrow IPC serialization. Define RPC interfaces as Python Protocol classes with automatic schema derivation, typed client proxies, and streaming support.

VGI (Vector Gateway Interface) — DuckDB extension for extending DuckDB in any language over Apache Arrow IPC. No C++/compilation required.

Python SDK for the VGI (Vector Gateway Interface) protocol — host DuckDB scalar, table, aggregate, and table-in-out functions in an external worker over Arrow IPC.

Go implementation of the vgi_rpc framework — Apache Arrow IPC-based RPC for high-performance data services

TypeScript SDK for the VGI (Vector Gateway Interface) protocol — host DuckDB scalar, table, aggregate, and table-in-out functions in an external worker over Arrow IPC.

Transport-agnostic RPC framework for Java built on Apache Arrow IPC — the Java port of vgi-rpc. Define services as Java interfaces; calls flow over pipe, subprocess, Unix-socket, shared-memory, or HTTP.

Java SDK for the VGI (Vector Gateway Interface) protocol — host DuckDB scalar, table, aggregate, and table-in-out functions in an external worker over Arrow IPC.

Go SDK for the VGI (Vector Gateway Interface) protocol — host DuckDB scalar, table, aggregate, and table-in-out functions in an external worker over Arrow IPC.

Apache Arrow Flight Client for Node.js

An opinionated config-driven Rust server that publishes Parquet and Delta datasets as fast, typed HTTP APIs from local disk or object storage, with interchangeable DuckDB or Arrow+DataFusion backends, JSON and Arrow IPC output, and production-ready features like auth, metrics, and hot reloads.
