Python Transformation in a Streaming Mapping

Python Transformation in a Streaming Mapping

Streaming mappings have additional processing rules that do not apply to batch mappings.
Consider the following restrictions:
  • When you close a Jep instance, you might not be able to call CPython modules.
  • Do not use the names
    inRowsList
    and
    outRowsList
    in the Python code. These names are reserved for the Scala code that the Spark engine uses to interact with the Python environment.
