問題文
A login workflow always begins with an event whose message contains the word that marks the sign-in attempt. The team wants each such event to start a new group. Which argument of the transaction command does that?
選択肢
- The connected argument, which decides whether an event that carries the required fields opens a new group.
- The endswith argument, which takes the same kind of expression and is evaluated first because groups are assembled from the newest event backwards.
- The startswith argument, which takes a search or eval expression that marks the start of a new group when an event satisfies it.
- The unifyends argument, which forces the first and last events to share the listed fields.
