Dask-expr – query optimization for faster Dask DataFrames

In plain words

Dask-expr is a query optimization tool designed to speed up Dask DataFrames, which are used for processing large datasets in parallel. It works by optimizing how data queries are structured and executed, reducing unnecessary computation. The tool is intended for data engineers and scientists who work with distributed data processing and need faster performance. Dask-expr launched in October 2023 and is available on GitHub for developers looking to improve their Dask-based workflows.

  Open-source, browser-local data exploration using DuckDB-WASM and PRQL2024 · github.com · ▲227

  Hey HN! We’ve built Pretzel, an open-source data exploration and visualization tool that runs fully in the browser and can handle large files (200 MB CSV on my 8gb MacBook air is snappy). It’s also reactive - so if, for example, you change a filter, all the data transform blocks after it re-evaluate automatically. You can try it here: https://pretzelai.github.io/ (static hosted webpage) or see a demo video here: https://www.youtube.com/watch?v=73wNEun_L7w You can play with the demo CSV that’s pre-loaded (GitHub data of text-editor adjacent projects) or upload…

  I built an open-source data pipeline tool in Go2024 · github.com · ▲200

  Every data pipeline job I had to tackle required quite a few components to set up: - One tool to ingest data - Another one to transform it - If you wanted to run Python, set up an orchestrator - If you need to check the data, a data quality tool Let alone this being hard to set up and taking time, it is also pretty high-maintenance. I had to do a lot of infra work, and while this being billable hours for me I didn’t enjoy the work at all. For some parts of it, there were nice solutions like dbt, but in the end for an end-to-end workflow, it didn’t work. That’s why I decided to build an…

  Dassana. JSON-native,schema-less logging solution built atop ClickHouse2022 · ▲25

  Hello HN, I’m Gaurav. Founder & CEO of Dassana. We are coming out of stealth today and would like to invite the community to give us a try. https://lake.dassana.io/ First, a bit of a backstory. I grew up with grep to search log files. The kind of person whose grep was aliased to grep -i. Then came along Splunk. It was a game-changer. For every single start-up I started (there are a few) I used Splunk and quite often we will run out of our ingestion quota. SumoLogic wasn’t cheaper either so we looked into DataDog. It was good until we started running issues with aggregate…

  Talanoa▲346

  Hi 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…
