pandas: 520ms Handles larger-than-RAM data If you have data that does not fit into memory, Polars' query engine is able to process your query (or parts of your query) in a streaming fashion. This drastically reduces memory requirements, so you might be able to process your 250GB dataset...

针对使用Pandas和PyPolars库的一些基本操作的上述基准时间数,我们可以观察到 PyPolars几乎比Pandas快2到3倍。 现在我们知道PyPolars有一个与Pandas非常相似的API,但仍没有涵盖Pandas的所有函数。比如说,PyPolars中就没有.describe()函数,相反我们可以使用df_pypolars.to_pandas().describe()。
I am used to pandas but in recent times I have come to greatly appreciate the memory efficiency and speed of manipulating and processing data in Polars especially as I continue to see them in kaggle competition notebooks. I am looking for good resources to get up to speed with polars. Thank...
