Columnar store for fast, lightweight logging
Founder here, Parseable is a lightweight log ingestion and query engine written in Rust. Parseable can ingest data from existing logging agents (FluentBit, LogStash, Vector, syslog-ng and more) using HTTP + JSON output. Ingested logs are stored as semi-indexed Parquet files (on disk or S3). You can query the data with builtin query engine using SQL or use a query engines of choice like Spark, Presto, Trino and so on. We also developed a Grafana data source plugin that lets you visualise log data via Grafana. Sample dashboard link in readme. As log data grew, our industry has responded with…
Columnar store for fast, lightweight logging launched on January 18, 2023 with 15 votes, #1,314 of 3,901 launches that month and more than 75% of that year's launches. The site was still online in September 2026, 3 years on.
In plain words
Parseable is a lightweight log ingestion and query engine built in Rust that accepts data from common logging agents via HTTP and JSON. It stores logs as semi-indexed Parquet files on disk or S3, then queries them using SQL through a built-in engine or external tools like Spark and Trino. The system includes a Grafana plugin for log visualization. Designed for developers and operations teams who want full control over log data without relying on managed services.

Parseable Log Storage2022 · parseable.com · ▲79Over the past few months, we've been building Prism; a fast, developer-first observability UI that's deeply integrated with our open-source database, Parseable. Prism is designed for engineers who debug distributed systems, sometimes at odd hours, and need answers right now, without having to deal with five different tools. Backstory: We spoke to dozens of observability practitioners in large enterprises. Across the board, we heard two things: (1)The RoI on observability tools is hard to justify. (2)OSS leads to tool sprawl, metrics in Grafana, logs in ELK, traces… somewhere. We wanted a…

Rust based log analytics with Parquet on S32023 · github.com · ▲13For write once, read many, immutable data types, Parquet on S3 is one of the most economical and scale approach. Every organisation I have talked to, in the last few years has attempted some form of Parquet on S3 implementation. However, these initiatives face challenges in standardising the approach for both ingesting and querying the data. Data quality, data governance and access control - everything becomes a challenge. We at Parseable are taking the Parquet on S3 approach and making it into an Enterprise grade product. Integrate easily with existing log agents and libraries. Built-in…
Parqeye – A CLI tool to visualize and inspect Parquet filesNov 2025 · github.com · ▲167I built a Rust-based CLI/terminal UI for inspecting Parquet files—data, metadata, and row-group-level structure—right from the terminal. If someone sent me a Parquet file, I used to open DuckDB or Polars just to see what was inside. Now I can do it with one command. Repo: https://github.com/kaushiksrini/parqeye

Talanoa▲341Hi HN, I’m a fullstack developer, and honestly, I’ve lost count of how many side projects I’ve worked on over the years. But one idea kept coming back to me: a different kind of email client. It first came to me in 2014: “What if we could handle emails more like conversations?” Every year, I’d revisit this concept in my “Build Notes.” Ten years later, no one had built exactly what I had in mind — so I finally decided to do it myself. That’s how Talanoa was born. I wanted something focused on people, not timelines. I was tired of marking messages as unread just to remember to reply later, or…

This works suprisingly well. Just give it instructions like "make it winter" or "remove the cars" and the photo is altered. Here are some examples of transformations it can make: Golden gate bridge: https://raw.githubusercontent.com/brycedrennan/imaginAIry/ma...

I integrated this new InstructPix2Pix model into imaginAIry (python library) so it's easy to use for python developers.

The project is called QueryStorm. It uses Roslyn to offer C# (and VB.NET) support in Excel, as an alternative to VBA. I've posted about it before, but a lot has changed since then so figured I'd share an update. The current version includes a host of new features, namely a C# debugger, support for NuGet packages, and the ability to publish Excel extensions to an "AppStore" (which is essentially a NuGet repository). The AppStore can be used by anyone with the (free) runtime component. Another great addition is the community license, which is a free license for individuals and small companies…

Hey HN! Some more info: I’m an NHS doctor and the founder of Pi-A (https://www.pi-a.io) which developed Lungy (https://www.lungy.app). Lungy is an app (iOS only for now) that responds to breathing in real-time and was designed to make breathing exercises more engaging and beneficial to do. It hopefully has many aspects of interest to the HN community – real-time fluid, cloth and soft body sims running on the phone’s GPU. My background is as a junior surgical trainee and I started building Lungy in 2020 during the first COVID lockdown in London. During COVID, there were…
