Chris Morgan commented on ARROW-7885:
-------------------------------------
What does supporting Dask DataFrames have to do with databases? Thanks
> [Python] pyarrow.serialize does not support dask dataframe
> ----------------------------------------------------------
>
> Key: ARROW-7885
> URL: https://issues.apache.org/jira/browse/ARROW-7885
> Project: Apache Arrow
> Issue Type: Wish
> Components: Python
> Reporter: Benjamin
> Priority: Minor
>
> 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).
