### Description
r-polars has the ability to export DataFrames via the Arrow C stream interface (pola-rs/r-polars#5, by @paleolimbot).

Edit: This would be similar to `df.update()` (see comments 2 and 3), but `df.supplement(df2)` would a) prioritize the non-null results in `df` and only add the values from `df2` that don't have corres…

The `asof_join` only needs all **non-null** values to be sorted, but it directly checks the sorted flag. This does not work for an example like this:
```python
left = pl.DataFrame({"x": [None, "a"…

### Describe the bug
I'm not sure if this is really a bug, but anyway… While experimenting with the operators, I noticed `+` is permitted between dataframes. However, the result seems very strange …

They work almost identically for `pandas.DataFrame`, and the former would work for `polars.DataFrame` and `pyarrow.Table`.
```python
import duckdb
import polars as pl
import prql_python as prql

It looks like our string to datetime utilities throws an error. This is a fairly common step while cleaning datasets, so it'd be nice to support it:
```python
import polars as pl
from functools i…

### Describe the workflow you want to enable
Currently, scikit-learn nowhere claims to support [pyarrow](https://arrow.apache.org/docs/python/) or [polars](https://www.pola.rs/). And indeed,
```py…

Disclaimer: I have not run this just a coupke of thoughts.
Use ibis-project as a dataframe code output that translates to many known backends incl duckdb, pandas, polars, spark
Use smart_open …

First of all very cool library, I was looking for something like this for a while. Curious why Float64 is faster. I assume under the hood type conversion?
