      • PYTHON-5562 investigate default values for withTransaction backoff parameters
        • Work is finished. Investigation done and findings presented to the larger DBX team at dbx offsite
      • PYTHON-5518 withTransaction API retries too frequently
        • Made a breakthrough on consistent test reproduction for withTransaction retry, convened on leveraging a "jitter constant" for the sake of maintaining determinism in tests. Confirmed feasibility across drivers teams and updated the spec and tests to reflect this.
      • PYTHON-5536 --> PYTHON 5517
        • Availability Workload (PERF-7078) merged
        • Python implementation currently under review PYTHON-5517
        • Spec PR in review (in sync with python implementation) DRIVERS-3218
      • What's the focus over the next two weeks?
        • Merging the Specifications PRs
        • Merging the implementations derivate of those Specification PRs
