⟩ What is business key?
This string is appended to the AE
tracking info appInfo field. The AE
tracking info for messages published is a
concatenation of bw + <processName> +
<jobID> + <businessKey>.
Note: It is a good idea to have all
publishers in a process use the same
business key. Only the most recent
publisher’s business key is used in the
tracking info for the message.
