doc/source/whatsnew/vX.X.X.rstfile if fixing a bug or adding a new feature.DataFrame.attrs seems to not be attached to pyarrow schema metadata as it is experimental. Added it to the pyarrow table (schema.metadata) so it persists when the parquet file is read back. One issue I am facing is DataFrame.attrs dictionary can't have int as keys as encoding it for pyarrow converts it to string, but not sure if this is a problem.
