问题概述

基于 Hacker News 帖子与评论,用户正在评估 Polars 2.0 作为 Pandas 替代方案的可行性,特别是在大规模预计算场景下的适用性。多位评论者提及 Pandas 为遗留项目,计划转向 DuckDB、Polars 或 PyArrow,但对何种工作负载下哪种工具更合适仍存疑。

I've used Polars before and can only recommend it.It's like you get a really good 'query planner' like a DB would give you, but for your notebooks/scripts/etc. Much better than pandas imo.

I'm not following the trends closely, but has Polars become a full replacement for Pandas? Are there use cases where one is better suited than the other?
