------------------------------
External issue URL: https://github.com/apache/arrow/issues/16657
> Write to parquet with InMemoryOutputStream
> ------------------------------------------
>
> Key: ARROW-1067
> URL: https://issues.apache.org/jira/browse/ARROW-1067
> Project: Apache Arrow
> Issue Type: Bug
> Components: Python
> Affects Versions: 0.4.0
> Environment: Debian 8.5, Anaconda Python 3.6, pyarrow 0.4.0a0
> Reporter: Chase Slater
> Priority: Minor
> Labels: documentation
>
> When I run the following (from the docs) python crashes during the
> pq.write_table statement. How would I go about writing a parquet file to a
> file buffer (e.g. for use with Azure Data Lake)?
> {code}
> import pyarrow as pa
> import pyarrow.parquet as pq
> table = pa.Table.from_pandas(df, timestamps_to_ms=True)
> with adl.open(my_file_path, 'wb') as f:
> output = pa.InMemoryOutputStream()
> pq.write_table(table, output) # crashes here
> f.write(output.get_result().to_pybytes())
> {code}
