Can this be merged into Pandas?
I’d be honored if something I built got incorporated into Pandas! That said, keeping aiopandas as a standalone package has the advantage of working with older Pandas versions, which is useful for workflows where upgrading isn’t feasible. I also can’t speak to the downstream implications of adding this directly into Pandas.
Pandas does not install tqdm by default.
That makes sense, and aiopandas doesn’t require tqdm either. You can pass any class with __init__, update, and close methods as the tqdm argument, and it will work the same. Keeping dependencies minimal helps avoid unnecessary breakage.
What about Dask?
I’m not a regular Dask user, so I can’t comment much on its internals. Dask already supports async coroutines (Dask Async API), but for simple async API calls or LLM requests, aiopandas is meant to be a lightweight extension of Pandas rather than a full-scale parallelization framework. If you’re already using Dask, it probably covers most of what you need, but if you’re just looking to add async support to Pandas without additional complexity, aiopandas might be a more lightweight option.

dask-cudf: https://docs.rapids.ai/api/dask-cudf/stable/ :
> Neither Dask cuDF nor Dask DataFrame provide support for multi-GPU or multi-node execution on their own. You must also deploy a dask.distributed cluster to leverage multiple GPUs. We strongly recommend using Dask-CUDA to simplify the setup of the cluster, taking advantage of all features of the GPU and networking hardware.

> cuDF implements a subset of the pandas API, while cudf.pandas will fall back automatically to pandas as needed.
> Can I use cudf.pandas with Dask or PySpark?
> [Not at this time, though you can change the dask df to e.g. cudf, which does not implement the full pandas dataframe API]
