How long does Temporal guarantee ID uniqueness?

From the docs:

Workflow Id: A unique identifier for a Workflow Execution. Temporal guarantees the uniqueness of an Id within a namespace. An attempt to start a Workflow with a duplicate Id results in an already started error.

Assuming a reuse policy of Reject Duplicate:

Does temporal guarantee this uniqueness for the duration of the retention period or forever? Do archival settings affect this at all?

Solution

  • The uniqueness is guaranteed while a workflow is open and then after it is closed up to the retention period.

    I filed a GitHub issue to separate out these two periods.
