描述

Currently between spark 2.x and spark 3.x batch ingestion lot of code is duplicated other than SparkSegmentMetadataPushJobRunner class. This ticket is to refactor the code to eliminate the duplicate code without breaking the compatibility. Code changes required are to :

  • Abstract common functionality into shared methods/classes.
  • Separate version-specific details.
  • Ensure the resulting codebase is cleaner and easier to maintain.

研究方向
Examine the code for Spark 2.x and 3.x batch ingestion, focusing on SparkSegmentMetadataPushJobRunner and related classes. Identify duplicated logic and design shared methods or parent classes to eliminate duplication while maintaining version specific behavior. Ensure backward compatibility by testing both versions.
