 - Improved the performance of the Jenkins3 hash computation used for partition key resolution. Across various input sizes, the updated implementation achieves up to 39% faster hash calculation, with the most notable gains seen for smaller keys (8–32 bytes), and consistent improvements across all sizes. The new approach maintains the exact bit-for-bit hash output while reducing overhead.  _(A community contribution, courtesy of [danielmarbach](https://github.com/danielmarbach))_

 - Updated retry policy behavior when the service is throttling and the `TryTimeout` is shorter than the standard throttling time of 30 seconds.  Previously, the operation was immediately canceled with a server busy exception.  With these changes, the operation will begin consuming retry attempts while throttling until either the server busy state is cleared or all configured retry attempts are exhausted.
