Task completion of many medium-input-payload activities in one task will cause issue with gRPC max message size. Temporal team is discussing solutions, the most common of which is likely having support for multi-RPC partial task completion.

Research direction

No files, tests, or entry points are named. Begin by clarifying the proposed multi-RPC partial task-completion contract with the Temporal team, then identify the affected task-completion RPC and compatibility tests; done means large task completions no longer hit the gRPC message-size limit while existing behavior remains compatible.
