Marco Neumann created ARROW-1276:
------------------------------------
Summary: Cannot serializer empty DataFrame to parquet
Key: ARROW-1276
URL: https://issues.apache.org/jira/browse/ARROW-1276
Project: Apache Arrow
Issue Type: Bug
Components: Python
Affects Versions: 0.5.0
Reporter: Marco Neumann
Priority: Minor
The following code fails with {{pyarrow.lib.ArrowInvalid: Invalid: chunk size
per row_group must be greater than 0}} but should not:
{noformat}
import pandas as pd
import pyarrow as pa
import pyarrow.parquet as pq
df = pd.DataFrame({'x': pd.Series([], dtype=int)})
table = pa.Table.from_pandas(df)
buf = pa.InMemoryOutputStream()
pq.write_table(table, buf)
{noformat}
I have a test and a fix prepared and will upstream both in the upcoming days.
