About this skill

What it does. Guides Vaex workflows for larger-than-RAM HDF5, Arrow, CSV and Parquet data: inspect schemas, open files, define virtual columns, filter, run delayed reductions and grouped statistics, plot aggregated grids, and export in chunks. It highlights operations that may materialise data and validates counts, units, joins and reopened outputs.

When to use it. For single-machine columnar scientific analysis, especially repeated reductions and histograms. Out-of-core processing does not make sorting, joins, large group dictionaries or many estimator fits memory-bounded.
