----------------------------------
Summary: [Parquet] Support LargeListArray
Key: ARROW-7731
URL: https://issues.apache.org/jira/browse/ARROW-7731
Project: Apache Arrow
Issue Type: Improvement
Reporter: marc abboud
For now it's not possible to write a pyarrow.Table containing a LargeListArray
in parquet. The lines
{code:java}
from pyarrow import parquet
import pyarrow as pa
indices = [1, 2, 3]
indptr = [0, 1, 2, 3]
q = pa.lib.LargeListArray.from_arrays(indptr, indices)
table = pa.Table.from_arrays([q], names=['no'])
parquet.write_table(table, '/test'){code}
yields the error
{code:java}
ArrowNotImplementedError: Unhandled type for Arrow to Parquet schema
conversion: large_list<item: int64>
{code}
