Summary of Changes

Hello, I'm Gemini Code Assist1! I'm currently reviewing this pull request and will post my feedback shortly. In the meantime, here's a summary to help you and other reviewers quickly get up to speed!

This pull request enhances the Apache Beam SDK by adding new parameters to the signatures of processElement and onTimer methods in DoFn. These additions include recordId, recordOffset, and fireTimestamp, which provide more context and control within the data processing pipeline. The changes also introduce new annotations to facilitate the use of these parameters and ensure they are accessed correctly within the appropriate method contexts.

Highlights

  • New Parameters: Added recordId, recordOffset, and fireTimestamp parameters to processElement and onTimer signatures, enhancing the flexibility of DoFn methods.
  • Annotations: Introduced new annotations (@CurrentRecordId, @CurrentRecordOffset, @FireTimestamp) to tag parameters in DoFn methods.
  • Exception Handling: Implemented specific UnsupportedOperationException messages to prevent incorrect access to recordId, recordOffset, and fireTimestamp outside their intended contexts.
