cc < Alekhya> < Smriti Satyan> can we please document this behavior

Ketan (kumare3) · Answer

Every execution that a user launches has optional `name` field If the name field is specified that is used as a de dupe identifier for idempotency Extremely useful if you are running workflows programmatically and want to safeguard against potential network errors etc It is safe to re execute with the same name An AlreadyExists error will be returned If you do not provide the name flyteadmin will generate one for you
