Indeed. feather was a library to exchange data between R and pandas dataframes. People tend to bash pandas but its creator (Wes McKinney) has changed the data ecosystem for the better with the learnings coming from pandas.

I know pandas has a lot of technical warts and shortcomings, but I'm grateful for how much it empowered me early in my data/software career, and the API still feels more ergonomic to me due to the years of usage - plus GeoPandas layering on top of it.

Really, prefer DuckDB SQL these days for anything that needs to perform well, and feel like SQL is easier to grok than python code most of the time.

chdb's new DataStore API looks really neat (drop in pandas replacement) and exactly how I envisioned a faster pandas could be without sacrificing its ergonomics

I switched to this as well and its mainly because explorations would need to be translated to SQL for production anyways. If I start with pandas I just need to do all the work twice.

Do people bash pandas? If so, it reminds me of Bjarne's quip that the two types of programming languages are the ones people complain about and the ones nobody uses.

polars people do - although I wouldn't call polars something that nobody uses.
Re:Apache Arrow is 10 years old by ayhanfuat on Thursday February 12, 2026 @11:06AM (#46990508)
I also use polars in new projects. I think Wes McKinney also uses it. If I remember correctly I saw him commenting on some polars memory related issues on GitHub. But a good chunk of polars' success can be attributed to Arrow which McKinney co-created. All the gripes people have with pandas, he had them too and built something powerful to overcome those.

I saw Wes speak in the early days of Pandas, in Berkeley. He solved problems that others just worked around for decades. His solutions are quirky but the work was very solid. His career advanced a lot IMHO for substantial reasons.. Wes personally marched through swamps and reached the other side.. others complain and do what they always have done.. I personally agree with the criticisms of the syntax, but Pandas is real and it was not easy to build it.

have these 'improvements' been backported to pandas now? i would expect it to close the gap over time.
Re:Apache Arrow is 10 years old by benrutter on Friday February 13, 2026 @03:21AM (#47000295)
Yes (mostly) is the answer. You can use arrow as a backend, and I think with v3 (recently released) it's the default.

The harder thing to overcome is that pandas has historically had a pretty "say yes to things" culture. That's probably a huge part of its success, but it means there are now about 5 ways to add a column to a dataframe.

Adding support for arrow is a really big achievement, but shrinking an oversized api is even more ambitious.

He missed talking about the poor extensibility of pandas. It's missing some pretty obvious primitives to implement your own operators without whipping out slow for loops and appending to lists manually.

People also love to hate R but data.table is light years better than pandas in my view
