-----------------------------------------
Summary: No support reading columns of type decimal(19,4)
Key: ARROW-1398
URL: https://issues.apache.org/jira/browse/ARROW-1398
Project: Apache Arrow
Issue Type: Bug
Components: Python
Affects Versions: 0.6.0
Environment: Ubuntu 16.04, Python 3.6
Reporter: Ludwik Bielczynski
I have a localy saved parquet database created in spark from querrying an SQL
database. When I run:
{code:python}
import pyarrow.parquet as pq
path = "path/to/parquet/dataset"
dataset = pq.ParquetDataset(path)
dataset.read()
{code}
an error indicating that there is no support for reading columns of type
decimal(19,4). It's quite a common type used in SQL databases and I saw in the
source code that there is an implementation for decimals. I'm stuck trying to
figuring out a solution. Is there a walk around (conversion of decimals to
integers during reading)?
