Is this a MQ implementation, or can this be used in place of e.g. something like protobufs and iroh/tonic? Does it have something akin to grants/capabilities/authorization? Does it have RPC? Can I have services speak a more privileged set of instructions/commands and clients needing auth to speak dumber/more high level administrative commands just like gRPC?
Also, is the performance due to the (what I assume is custom) zero copy serialization?
The landing page simply states it's essentially "fast messaging" but beyond that it's not entirely clear when I'd use this or what its features/limitations are.
There are a bunch of things that sum up to the overall performance gains - using Rust, thread-per-core architecture + shared-nothing (think of Seastar), custom zero-copy serialization, io_uring for disk * network I/O, and VSR-based consensus (inspired by TigerBeetle) - we simply build all this stuff from the ground up to make the most out of modern hardware and Kernel features, with a custom protocol on top (but the Kafka proxy/gateway is also WiP). And there are also connectors (sink, source), benchmarking runtime, CLI and so on.

It’s been quite a journey, from a small Rust message-streaming experiment in 2023 to an independent Apache project with a growing community. And its biggest feature yet, being the Viewstamped Replication Revisited (VSR) clustering, is coming soon.
