AlterLab Polars
技能 活跃Part of the AlterLab Academic Skills suite. Fast in-memory DataFrame library for datasets that fit in RAM. Use when pandas is too slow but data still fits in memory. Lazy evaluation, parallel execution, Apache Arrow backend. Best for 1-100GB datasets, ETL pipelines, faster pandas replacement. For larger-than-RAM data use dask or vaex.
To offer a significantly faster in-memory DataFrame library for datasets that fit within RAM, serving as a high-performance alternative to pandas for ETL pipelines and data analysis.
功能
- Fast in-memory DataFrame processing
- Lazy evaluation for query optimization
- Parallel execution for multi-core performance
- Apache Arrow backend for efficient data handling
- Expressive API for complex data transformations
使用场景
- Replacing slow pandas operations for datasets fitting in RAM
- Optimizing ETL pipelines for faster data processing
- Performing complex data analysis and transformations efficiently
- Working with datasets in the 1-100GB range
非目标
- Handling datasets larger than available RAM (use dask or vaex)
- Replacing specialized database connectors
- Providing a full-fledged analytics platform beyond DataFrame operations

Chdb Datastore
95与 ClickHouse 性能兼容的即插即用 pandas 替代品。使用 `import chdb.datastore as pd`（或 `from datastore import DataStore`）并编写标准的 pandas 代码 — API 相同，在大数据集上速度提升 10-100 倍。支持 16 种以上数据源（MySQL、PostgreSQL、S3、MongoDB、ClickHouse、Iceberg、Delta Lake 等）和 10 种以上文件格式（Parquet、CSV、JSON、Arrow、ORC 等）以及跨源连接。当用户希望使用 pandas 风格的语法分析数据、加速缓慢的 pandas 代码、将远程数据库或云存储作为 DataFrame 查询，或连接不同来源的数据时，请使用此技能 — 即使他们没有明确提及 chdb 或 DataStore。请勿用于原始 SQL 查询、ClickHouse 服务器管理或非 Python 语言。

Market Movers
100When the user wants to track App Store chart rank changes, find top gainers and losers, detect breakout apps entering the top 100, or identify apps dropping out of charts. Also use when the user mentions "chart movers", "rank changes", "who's rising", "who's falling", "new chart entries", "top gainers", or "market shifts". For broader market overview, see market-pulse.
