> Priority: Minor
> Fix For: 0.6.0
>
>
> 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.
