Key: SPARK-56413
URL: https://issues.apache.org/jira/browse/SPARK-56413
Project: Spark
Issue Type: Sub-task
Components: Spark Core, SQL
Affects Versions: 4.2.0
Reporter: Haiyang Sun
According to the SPIP, we would like to use a unified gRPC protocol for Spark
to process UDFs in different workers (languages) based on the worker
specification.
This ticket tracks the definition of the udf proto, and how the WorkerSession
interface can be implemented and later used by Spark.
