Does anybody here know dataframe systems that are able to handle file sizes bigger than the available RAM? Is polars able to handle this? I am only aware of disk.frame (diskframe.com), but don't know how well it performs.
With regard to Vaex, I would really be interested in an independent benchmark comparing it to dask, spark, data.table etc. However, I have seen in the comments that others also can't find that.

It has pandas, dask, Spark, data.table, Polars, etc. Sadly, Vaex is currently missing from this suite.
