Alexis Benoist created SPARK-9488:
-------------------------------------
Summary: pyspark.sql.types.Row very slow when used named arguments
Key: SPARK-9488
URL: https://issues.apache.org/jira/browse/SPARK-9488
Project: Spark
Issue Type: Bug
Components: PySpark
Affects Versions: 1.4.0
Environment:
Reporter: Alexis Benoist
We can see that the implementation of the Row is accessing items in O(n).
https://github.com/apache/spark/blob/master/python/pyspark/sql/types.py#L1217
We could use an OrderedDict instead of a tuple to make the access time in O(1).
Can the keys be of an unhashable type?
I'm ok to do the edit.
Cheers,
Alexis.
