Added
ExternalPayloadTransferStatsand a correspondingexternal_payload_transfer_statsfield onRespondWorkflowTaskCompletedRequest. The message carries a list of per-storage-driver entries, each with upload/download counts and byte totals.ExternalPayloadTransferStatsis in common/v1 so we can extend it to other requests in the future if needed, e.g.StartWorkflowExecutionRequest.Why?
Lets SDKs report external payload transfer activity per workflow task so the server can emit workflow task latency metrics tagged by driver, and correlate latency with transferred bytes/count.
Breaking changes
None.
