>                 Key: ARROW-7885
>                 URL: https://issues.apache.org/jira/browse/ARROW-7885
>             Project: Apache Arrow
>          Issue Type: Wish
>          Components: Python
>            Reporter: Benjamin
>            Priority: Minor
>              Labels: pyarrow-serialization
>
> Currently pyarrow knows how to serialize pandas dataframes but not dask dataframes.
> {code:java}
> SerializationCallbackError: pyarrow does not know how to serialize objects of type <class 'dask.dataframe.core.DataFrame'>. {code}
> Pickling the dask dataframe foregoes the benefits of using pyarrow for the sub dataframes.
> Pyarrow support for serializing dask dataframes would allow storing dataframes efficiently in a database instead of a file system (e.g. parquet).
