This PR ensures that when the C++ SDK reconnects write streams for Rapid objects, it includes the write_handle in the resume request. This enables fast resume instead of slow takeover, significantly reducing reconnect latency and avoiding offset mismatch errors.

Summary of Changes

Hello @shubham-up-47, 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 C++ SDK's handling of Rapid object write stream reconnections. By ensuring that the write_handle is included in resume requests, the system can leverage a more efficient "fast resume" process. This optimization is crucial for reducing reconnection latency and preventing data integrity issues like offset mismatch errors, ultimately leading to more robust and performant object writing operations.

Highlights

  • Enabled Fast Resume: The C++ SDK now includes the write_handle in resume requests for Rapid object write streams.
  • Improved Reconnection Efficiency: This change allows for a "fast resume" mechanism, replacing the less efficient "slow takeover" process.
  • Reduced Latency and Errors: The update significantly decreases reconnect latency and prevents potential offset mismatch errors during stream reconnections.

Code Review

This pull request correctly enables fast resume for rapid object write streams by including the write_handle in the resume request. The implementation is straightforward and the new tests properly cover both the positive and negative cases. I have a couple of suggestions to simplify the test code by removing redundant lines, improving conciseness and maintainability.
