Hyukjin Kwon created SPARK-60977:
------------------------------------
Summary: Export StatefulProcessor and TwsTester from
pyspark.sql.streaming in Spark Connect Rust as PySpark does
Key: SPARK-60977
URL: https://issues.apache.org/jira/browse/SPARK-60977
Project: Spark
Issue Type: Bug
Components: Connect
Affects Versions: connect-rust-4.3.0
Reporter: Hyukjin Kwon
In PySpark 4.3.0, {{pyspark.sql.streaming}} exports {{StatefulProcessor}},
{{StatefulProcessorHandle}} and {{TwsTester}}, the latter from the module
{{pyspark.sql.streaming.tws_tester}} added in 4.2.0. In the Rust-backed Python
client, {{from pyspark.sql.streaming import StatefulProcessor}} raises
{{ImportError}}, and the {{tws_tester}} module is missing. Export them, and
vendor {{tws_tester}}, which is pure Python, as in PySpark.
