      Summary

      Expand the Python test suites to validate asynchronous step-down workflows, covering concurrent reads/writes during an async step-down event.

      Motivation

      Python test suites provide targeted functional coverage for specific WiredTiger behaviors. This ticket ensures async step-down is exercised across the various timestamp modes, prepared transactions, and fast truncate paths.

      Scope

      • Concurrent read/write cursor operations transitioning during an async step-down event
      • Different timestamp setting modes (commit timestamp, durable timestamp, read timestamp, etc.)
      • Prepared transactions during async step-down
      • Fast truncate during async step-down

      Definition of Done

      • Python test suites cover async step-down with:
        • Concurrent CRUD cursor ops(all cursor operations)
        • Various timestamp setting patterns
        • Prepared transaction workflows
        • Fast truncate scenarios
