Can you put Arrow data in xarray? Arrow is interchangeable with Awkward Array, so having Arrow can be seen as equivalent to having Awkward. The [ak.to_arrow](https://awkward-array.readthedocs.io/en/latest/_auto/ak.to_arrow.html) and [ak.from_arrow](https://awkward-array.readthedocs.io/en/latest/_auto/ak.from_arrow.html) functions are...

> Bit of a tangent, but it might be worthwhile to write up [a Data Array API issue](https://github.com/data-apis/array-api/issues) about the Awkward Array use case. We already talked about it here:...

I'm just catching up to all of this, but I can answer a few questions now. > I believe it does have [copy, just not as a method](https://awkward-array.readthedocs.io/en/latest/_auto/ak.copy.html). We might...

I'd like to know more about this, though it's a lot to take in at once. Would you like to talk sometime so that I can learn more about anndata...

> I would note that there are some things in the awkward array api that will change ([scikit-hep/awkward-1.0#1151](https://github.com/scikit-hep/awkward-1.0/discussions/1151)), but that's mostly down the line stuff. In the three levels of...

This is very interesting! We had been [planning to reintroduce](https://github.com/scikit-hep/awkward/wiki#pandas-integration) "Awkward Array as a Pandas column" by creating a new library that is external to `awkward` itself, so that *...

This is an example of how an Awkward Array can be wrapped as a Pandas column: https://github.com/martindurant/awkward_extras/tree/main/awkward_pandas (See also [AwkwardSeries](https://github.com/martindurant/awkward_extras/blob/main/awkward_pandas/series.py) and [tests](https://github.com/martindurant/awkward_extras/blob/main/awkward_pandas/tests/test_series.py).) Pandas ExtensionArrays can only be one-dimensional, so we...

> In [scverse/scirpy#327 (comment)](https://github.com/scverse/scirpy/issues/327#issuecomment-1172977130) it was suggested to store AIRR data in `.X`. Following this comment, I gather that what you mean by "`.X`" is a [BumpyMatrix](https://bioconductor.org/packages/release/bioc/html/BumpyMatrix.html), which is a...

Benefits of one over the other: if "cell1, cell2, cell3..." are part of a sequence, especially if it's a dimension that can grow large, then it should be an ak.Array,...

It's not the sort of thing that would be documented as such; it's an artifact of how TTrees get written when an error interrupts the write. The completely different place...
