Why HN links it

HN readers link Vaex, a Python DataFrame library for out-of-core and larger-than-memory data, as an alternative to pandas and Dask. Commenters discuss it in threads on Dask, Arrow and DataFrames.

Summarised by Claude from a sample of 6 HN comments that link here. Each comment is marked recommending, critical or neutral (citing without judging); how this works.

  1. I was mainly looking at Dask for the purpose of a more better Pandas DataFrame, but it seems like it's actually not that much better, just more distributed. It's like Dask is trying to do too many things and there doesn't do most of them well enough. While I haven't tried it, vaex[1] seems much better, since it specifically to only address one pain point, which is to address the inefficiencies of the pandas DataFram…

  3. FWIW, I'm moving towards [vaex]( https://vaex.io/docs/ ) for out of core python stuff Dask is well built but is fundamentally flawed by tacking together pandas structures with multiprocessing, rather than having a fundamentally efficient underlying structure.

  5. Hi, how does this compare to Vaex? https://vaex.io/docs/tutorial.html Vaex can join larger than memory datasets, but it doesn't support SQL per-se, it uses it's own lazy dataframe DSL.

  7. Thanks, glad you find Vaex useful. Indeed, for small data there is not much to gain, at least this is not the focus of this article. Although even with small amounts of the, the automatic pipelines are useful https://vaex.io/blog/ml-impossible-train-a-1-billion-sample-...

  8. Why this hybrid dataframe? [1]: > [Arrow] adoption will take time, and most people are probably more comfortable seeing NumPy arrays. Therefore a Vaex version 4 a DataFrame can hold both NumPy arrays and Apache Arrow arrays to make the transition period easier. There seems to be agreement that Apache Arrow is the future of dataframes across ML ecosystems. I didn't realize this transition impacted NumPy arrays in add…

  9. There are many packages that can do that, like Vax [1] and Dask [2]. I don't know exactly your workflow. But the concurrency in python is limited to multiprocessing, which is much expensive than threads which usually a typical streaming parallelizer will use outside python world.
