[jira] [Updated] (ARROW-7885) [Python] pyarrow.serialize does not
support dask dataframe
[ https://issues.apache.org/jira/browse/ARROW-7885?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Joris Van den Bossche updated ARROW-7885:
-----------------------------------------
Labels: pyarrow-serialization (was: )
> [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
> 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).
