研究方向

Start in SyncWorkflowContext.executeLocalActivity, which the issue identifies as serializing arguments before checking replay state; trace how doNotIncludeArgumentsIntoMarker affects marker creation and how local activities receive deserialized inputs. Check the relevant local-activity tests and add coverage for the option, including replay. Done means arguments bypass serialization and deserialization when they are not recorded in the marker, without changing marker or replay behavior.

描述

enhancement

When user sets LocalActivityOptions.setDoNotIncludeArgumentsIntoMarker(true)
local activity arguments (inputs) are not written to event history. However they are still serialized and deserialized even tho they run in same process. Arguments are serialized always, including during replay. Deserialized when local activity runs.

SyncWorkflowContext.executeLocalActivity serializes the arguments as its first thing, before check if workflow is replaying.

doNotIncludeArgumentsIntoMarker controls only if serialized arguments end up in marker event, not if serialization happens or not

Why it matter:
this extra serialization / deserialization can create cpu cost when running payload encryption

Ask:
When local activity arguments are not written to marker event, pass them to local activity directly instead of serializing and deserializing them.
