  • Building a faster hash table for high performance SQL joins
    3 projects | news.ycombinator.com | 20 Dec 2023
    Looks like full keys are always compared if hash codes test equal, which is what I'd expect. For example: https://github.com/questdb/questdb/blob/master/core/src/main...
  • K3s Traefik Ingress - configured for your homelab!

    But of course, I want to run a QuestDB instance on my node, which uses two additional TCP ports for Influx Line Protocol (ILP) and Pgwire communication with the database. So how can I expose these extra ports on my node and route traffic to the QuestDB container running inside of k3s?
  • Annotations in Kubernetes Operator Design

    In this post, I will detail a way in which I recently used annotations while writing an operator for my company's product, QuestDB. Hopefully this will give you an idea of how you can incorporate annotations into your own operators to harness their full potential.
  • Leveraging Rust in our high-performance Java database
    3 projects | news.ycombinator.com | 20 Sep 2023
    QuestDB engineer here:

    It's true that our non-idiomatic Java usage denies us some of the benefits typically associated with Java programming. Automatic memory management and the old "Write Once, Run Anywhere" paradigm are difficult to maintain due to our reliance on native libraries and manual memory management.

    I see two classes of reasons for choosing Java:

    1. Historical: The QuestDB codebase predates Rust. According to Wikipedia, the initial Rust release was in 2015. The oldest commit in the QuestDB repo is from 2014: https://github.com/questdb/questdb/commit/95b8095427c4e2c781... What were the options back in 2014? C++? Too complicated. C? Too low-level. Pretty much anything else? Either too slow or too exotic.

    2. Technical: Java, even without GC or WORA, still offers some advantage.

    QuestDB is a time-series database that offers fast ingest speeds, InfluxDB Line Protocol and PGWire support and SQL query syntax. QuestDB is composed mostly in Java, and we've learned a lot of difficult and interesting lessons. We're happy to share them with you.

  • any opinion good or bed about a code that smells?
    3 projects | /r/java | 28 Jan 2023
    The Java API implementation is problematic due to over allocating which results in a great deal of overhead. Projects like QuestDB don't use the Java API much to reduce GC thrashing. It results in a DB that outperforms C++ counterparts.

  • How we've approached reliability & cost savings for our strapped SaaS
    2 projects | /r/SaaS | 12 Dec 2022
    We've come a long way from my first iteration where I ran speedtest-cli in a docker container that posted data to mysql all hosted on a single ec2 instance in AWS, with absolutely no fault tolerance or scaling. Now we host our stack in containers running in GKE, split into their own microservices, passing data between our services using pubsub, and using a bad ass new TimeSeries database QuestDB. Additionally, our team has rewritten our local client in Go which allows us to run on just about any kind of device / OS -- broadening our market to so much more than folks wanting to measure their internet from their PC at home.
