[github-actions]

Checks are failing. Will not request review until checks are succeeding. If you'd like to override that behavior, comment assign set of reviewers

[github-actions]

Assigning new set of reviewers because Pr has gone too long without review. If you would like to opt out of this review, comment assign to next reviewer:

R: @damondouglas for label java.
R: @damondouglas for label io.
R: @johnjcasey for label kafka.

Available commands:

• stop reviewer notifications - opt out of the automated review tooling
• remind me after tests pass - tag the comment author after tests pass
• waiting on author - shift the attention set back to the author (any comment or push by the author will return the attention set to the reviewers)

Reminder, please take a look at this pr: @damondouglas @damondouglas @johnjcasey

Going to move this into a draft state, will clean up and send for review again soon.
