> 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)?
