Benjamin created ARROW-7885:
-------------------------------
Summary: Serialize dask dataframe
Key: ARROW-7885
URL: https://issues.apache.org/jira/browse/ARROW-7885
Project: Apache Arrow
Issue Type: Wish
Reporter: Benjamin
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).
