----------------------------------
Summary: Python Serialization Fails with Nulls
Key: SEDONA-153
URL: https://issues.apache.org/jira/browse/SEDONA-153
Project: Apache Sedona
Issue Type: Bug
Reporter: Doug Dennis
The following currently fail due to Shapely not liking nulls/Nones:
{code:python}
def test_null_deserializer(self):
result = self.spark.sql("select cast(null as geometry)").collect()[0][0]
assert result is None
def test_null_serializer(self):
data = [
[1, None]
]
schema = t.StructType(
[
t.StructField("id", IntegerType(), True),
t.StructField("geom", GeometryType(), True),
]
)
self.spark.createDataFrame(
data,
schema
).createOrReplaceTempView("points")
count = self.spark.sql("select count from points").collect()[0][0]
assert count == 1
{code}
The solution is to add some null guards to methods in the python GeometryType
class. I can make a PR for this but I wasn't sure if I needed to wait for this
issue to be approved or acknowledged or something :)
