-----------------------------------
Summary: 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
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}
