Alexis Benoist updated SPARK-9488:
----------------------------------
Summary: pyspark.sql.types.Row very slow when using named arguments (was:
pyspark.sql.types.Row very slow when used named arguments)
> pyspark.sql.types.Row very slow when using 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
> Labels: performance
>
> 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.
