vaex-dataframes

What problem does it solve?

This Skill tackles the challenge of analyzing datasets that are too large to fit into your computer's RAM, enabling efficient processing and exploration of massive tabular data.

Core Features & Use Cases

• Out-of-Core Processing: Works with datasets from 10 GB to terabytes without loading them entirely into memory.
• Lazy Evaluation: Computations are performed only when needed, optimizing performance.
• Data Formats: Supports HDF5, Apache Arrow, Parquet, and CSV, with efficient memory-mapping for HDF5 and Arrow.
• Use Case: Analyze astronomical catalogs, financial time series, or large scientific datasets that exceed available RAM, performing aggregations, filtering, and visualization interactively.

Quick Start

Use the vaex-dataframes skill to open the file 'large_dataset.hdf5' and print its shape.
