Products that do what Que, a Ruby-PostgreSQL job queue with ~20x the throughput of DelayedJob does

Hi everyone - I wrote a job queue called Que, which uses Postgres' advisory locks to manage jobs very efficiently. My goal is to make it easy to cover jobs with the same ACID guarantees as the rest of your data. It won't be as fast as a dedicated or Redis-backed queue, but I expect it will be fast enough for many use-cases. https://github.com/chanks/que The 20x figure comes from a benchmark I ran on an AWS c3.8xlarge instance - this number will change depending on your hardware. The code for the benchmark (and some more detailed results) is here:…

   PostgreSQL performance and cost across 23 EC2 instance types▲97

   Hey! I'm Andrei. I got frustrated by how people tend to build overcomplicated backend systems, being "motivated" by big tech case studies and popular books. So, I started exploring lean architecture, and building my digital garden of ideas, approaches and data that align with this direction. Here I want to present one of the tools – Sizing tool for PostgreSQL. I've benchmarked PostgreSQL on different EC2 instances and disks, with different initial data sets to see performance that these instances can give you. And I've built a tool to visualize this data, which I welcome you to explore. So,…

    Pq – Simple, durable background tasks in Python using Postgres▲5

    At work we were using python-rq for background tasks. It does the job for simple things, but we kept bumping into limitations. We needed to schedule tasks hours / days out and trust they'd survive a restart. We wanted periodic tasks with proper overlap control. So we built a scheduling / enqueuing system around Postgres to bring these durability capabilities to python-rq. This worked fine for a while but was trickier to reason about due to its more complicated architecture (we'd run two separate services just for getting jobs from Postgres into the rq Redis queue, plus N actual…

    Show HN: SerenDB – Neon PostgreSQL fork optimized for AI agent workloads We forked Neon to make database operations faster and safer for AI agents. The goal is to enable instant experimentation with production data and catch prompt injection attacks before they hit your DB. The open-source repo is at https://github.com/serenorg/serendb The coolest current features are: 1. Time-travel queries: Query your database as it existed at any timestamp. SELECT * FROM orders AS OF TIMESTAMP '2024-01-15 14:30:00'. Essential for debugging agent decisions and auditing what data an…

    Siege - Real time data pipeline with a single command▲6

    Hi HN, we are so excited to be sharing this on here! Siege is the fastest and the simplest way to spin up a real-time data pipeline, which you can then query, filter, visualize with just clicks of some buttons, no need for any instrumentation or code changes. It works by capturing JSON data from your API transactions, transforming this data, and then storing it in an optimized columnar database for easy and fast querying. I've put together a 3-minute demo on Loom just now, showing you how I made real time dashboards in minutes:…

    Instant streaming APIs with built-in auth for new or existing Postgres▲6

    Hey HN! We recently launched a new capability to Hasura GraphQL Engine: Streaming Subscriptions for Postgres. Today we have a variety of solutions to ingest and store a large amount of data or a stream of data. However, once this data has been captured, securely exposing this data as a continuous stream to a large number of HTTP clients concurrently is a challenge. These are the challenges that Hasura aims to address: 1. Allow for Authorization rules so that clients can only consume the subset of the stream they have access to 2. Prevent missing events and allow each client to move through…
