  • Readyset: A MySQL and Postgres wire-compatible caching layer
    5 projects | news.ycombinator.com | 21 Feb 2024
    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.

    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.

  • Streaming processing in Python using Timely Dataflow with Bytewax

    Bytewax is a Python native binding to the Timely Dataflow library (written in Rust) for building highly scalable streaming (and batch) processing pipelines.
  • Alternative Kafka Integration Framework to Kafka Connect?
    3 projects | /r/apachekafka | 21 Jun 2022
    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.
  • [AskJS] JavaScript for data processing
    5 projects | /r/javascript | 27 May 2022
    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.

    > In the simplest case, I'm talking about regular SQL non-materialized views which are essentially inlined.

    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.

  • 7 Real-Time Data Streaming Tools You Should Consider On Your Next Project
    2 projects | dev.to | 20 Mar 2021
    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.

  • Unexpected downsides of UUID keys in PostgreSQL
    6 projects | news.ycombinator.com | 22 Jun 2023
    We use a macaddr8 that embeds a wall-clock timestamp (so they're ascending order, achieving data locality) with some additional randomness. It's worked really well for us:

    https://github.com/estuary/flow/blob/master/supabase/migrati...

    we use macaddr8 instead of bigint, because it has a postgres serialization / JSON encoding which lossless-ly round-trips with browsers and it works well with PostgREST. The same CANNOT be said for bigint, which is a huge footgun.

  • Need Advice on Real-Time Data Synchronization from PostgreSQL to BigQuery: Airbyte vs. CloudQuery?
    1 project | /r/dataengineering | 16 May 2023
    I can't claim to know much about CloudQuery, but we are an open-source platform with CDC connectors from PostgreSQL and materializations to BQ and elsewhere. We also have fully-managed connectors if you don't want to deal with hosting.
  • DAG orchestration for streaming data?
    3 projects | /r/dataengineering | 10 May 2023
    This is essentially how we model things in Flow (disclosure: I work there). We call them Derivations, which are data products that are built (derived) from other data products. Each data product (we call them Collections) is backed by a set of append-only logs, so they can be read by many different consumers at different times. IDK if our product can work for you since we don't (yet) support stuff like MQTT, but there's a pretty generous free tier if you'd be able to push the data over HTTP. Either way, I just think it's cool that others have independently arrived at similar ideas about how to model streaming tasks!
