[jira] [Created] (SPARK-21296) Avoid per-record type dispatch in PySpark createDataFrame schema verification

Hyukjin Kwon created SPARK-21296:
------------------------------------

             Summary: Avoid per-record type dispatch in PySpark createDataFrame schema verification
                 Key: SPARK-21296
                 URL: https://issues.apache.org/jira/browse/SPARK-21296
             Project: Spark
          Issue Type: Improvement
          Components: PySpark
    Affects Versions: 2.2.0
            Reporter: Hyukjin Kwon


Here, we do the type dispatch per record - https://github.com/apache/spark/blob/d935e0a9d9bb3d3c74e9529e161648caa50696b7/python/pyspark/sql/types.py#L1252-L1366 and
https://github.com/apache/spark/blob/d935e0a9d9bb3d3c74e9529e161648caa50696b7/python/pyspark/sql/session.py#L517-L537

This requires per-record operation cost. We should get rid of this.
