# Vaex

Work a table far bigger than your machine's memory

## What this does

Sometimes the file is simply bigger than the memory on your machine, and the usual DataFrame tools stop working. This lets you filter, aggregate, plot and build models over tables that large - up to billions of rows - by not loading it all at once. Reach for it when a CSV, HDF5, Arrow or Parquet file is the problem.

### Top 3 things it does for you

- Analyze a file too big to load
- Get fast statistics over a huge table
- Plot data that will not fit in memory

A scan is named by the exact content it read, not by a version number. A different version is a different artifact, and nothing here applies to a version AIR has not scanned.

## About Vaex

Processing and analyzing large tabular datasets - into the billions of rows - that exceed the RAM available to you.

Vaex works out-of-core, with lazy evaluation, fast aggregations, visualization of big data, and machine learning on large datasets.

Apply it when the task is a large CSV, HDF5, Arrow or Parquet file: fast statistics over a massive table, visualizing big data, or building ML pipelines that do not fit in memory.

## Questions

### Is Vaex safe to install?

AIR scanned this exact version of Vaex and flagged nothing. AIR's verdict: safe. The verdict is named by the content that was read, at commit 93124850ef08, so it cannot drift onto a version nobody scanned. The full report is at https://airmarket.ai/security/vaex.

### How do I install Vaex?

Open https://airmarket.ai/app/vaex on Air Market and use the install action: Air Market hands Claude a prompt naming this exact skill, and Claude sets it up. Source, pinned to the exact commit this listing describes: https://github.com/k-dense-ai/scientific-agent-skills/tree/93124850ef08487e423165554c54f0b333d5631d/skills/vaex. Install from that link, not the branch.
