timely-dataflow VS node_crunch

They have a bit about their technical foundation here[0].

Given that Readyset was co-founded by Jon Gjengset (but has apparently since departed the company), who authored the paper on Noria[1], I would assume that Readyset is the continuation of that research.

So it shares some roots with Materialize. They have a common conceptual ancestry in Naiad, where Materialize evolved out of timely-dataflow.

And systems like timely dataflow, https://github.com/TimelyDataflow/timely-dataflow

Project looks cool! Glad you open sourced it. It could use some comments in the code base to help contributors ;). I also like the datafusion usage, that is awesome. BTW I work on github.com/bytewax/bytewax, which is based on https://github.com/TimelyDataflow/timely-dataflow another Rust dataflow computation engine.

Just found this https://github.com/TimelyDataflow/timely-dataflow and my heart skipped a beat.

Bytewax is a Python native binding to the Timely Dataflow library (written in Rust) for building highly scalable streaming (and batch) processing pipelines.

I am working on Bytewax, which is a Python stream processing framework built on Timely Dataflow. It is not exactly a Kafka integration framework because it is a more of a general stream processing framework, but might be interesting for you. We are focused on enabling people to more easily debug, containerize, parallelize and customize and less on enabling a declarative integration framework. It is still early days for us! And we are looking for feedback and ideas from the community.

We used to use a library called Pond.js, https://github.com/esnet/pond, but the reliance on Immutable.JS caused some performance pitfalls, so we wrote a system from scratch that deals with data in a batched streaming fashion. A lot of the concepts were borrowed from a Rust library called timely-dataflow, https://github.com/TimelyDataflow/timely-dataflow.

Though the name "Dataflow" might be an unfortunate name conflict with another Rust project: https://github.com/TimelyDataflow/timely-dataflow

I see that now -- makes sense!

> Wish we had some better database primitives to assemble rather than building everything on Postgres - its not ideal for a lot of things.

I'm curious to hear more about this! We agree that better primitives are required and that's why Materialize is written in Rust using using TimelyDataflow[1] and DifferentialDataflow[2] (both developed by Materialize co-founder Frank McSherry). The only relationship between Materialize and Postgres is that we are wire-compatible with Postgres and we don't share any code with Postgres nor do we have a dependence on it.

Under the hood, Materialize uses Timely Dataflow (TDF) as the stream-processing engine. This allows Materialize to take advantage of the distributed data-parallel compute engine. The great thing about using TDF is that it has been in open source development since 2014 and has since been battle-tested in production at large Fortune 1000-scale companies.

I've written my own crate called node-crunch for distributed computing.

This looks really nice! It has encryption and compression is planned for the next release. I've developed node_crunch, a crate for distributed computing and designed the protocols myself. I think that Zenoh could make my life a lot easier ;-) I'll definitely try it out!

You may be interested in darwin-rs, a crate for evolutionary algorithm that I'm working on. It uses multiple threads to speed things up, but I'm currently implementing node-crunch support, so that it can run on a cluster.

Nice! I'm currently working on node_crunch a crate for distributed computing. I've modified an existing ray tracer to run on a cluster. If you're interested you can have a look at the code.

I'm currently working on node_crunch.
