Use this skill for processing and analyzing large tabular datasets (billions of rows) that exceed available RAM. Vaex excels at out-of-core DataFrame operations, lazy evaluation, fast aggregations, efficient visualization of big data, and machine learning on large datasets. Apply when users need to work with large CSV/HDF5/Arrow/Parquet files, perform fast statistics on massive datasets, create visualizations of big data, or build ML pipelines that do not fit in memory.

使用此技能处理和分析超出可用内存的大型表格数据集（数十亿行）。Vaex 在外部存储 DataFrame 操作、惰性求值、快速聚合、大数据高效可视化以及大规模数据集的机器学习方面表现卓越。当用户需要处理大型 CSV/HDF5/Arrow/Parquet 文件、对海量数据集进行快速统计分析、创建大数据可视化图表，或构建无法完全装入内存的机器学习流水线时，适用于此场景。
