userMetadata​

• Optional userMetadata: null | IUserMetadata

Metadata on the event. This is often carried over from commands and client calls. Most events won't have this information, and how this information is used is dependent upon the interface that reads it.

Current well-known uses: workflow_execution_started_event_attributes - summary and details from start workflow. timer_started_event_attributes - summary represents an identifier for the timer for use by user interfaces.

version​

• Optional version: null | Long

TODO: What is this? Appears unused by SDKs

workerMayIgnore​

• Optional workerMayIgnore: null | boolean

Set to true when the SDK may ignore the event as it does not impact workflow state or information in any way that the SDK need be concerned with. If an SDK encounters an event type which it does not understand, it must error unless this is true. If it is true, it's acceptable for the event type and/or attributes to be uninterpretable.
