Options for messages published to JetStream
Properties
A string identifier used to detect duplicate published messages.
If the msgID is reused within the stream's duplicate_window,
the message will be rejected by the stream, and the PubAck will
mark it as a duplicate.
headers: MsgHdrs
Headers associated with the message. You can create an instance of MsgHdrs with the headers() function.
expect: Partial<{ lastMsgID: string; streamName: string; lastSequence: number; lastSubjectSequence: number; }>
Set of constraints that when specified are verified by the server. If the constraint(s) doesn't match, the server will reject the message. These settings allow you to implement deduplication and consistency strategies.
