the first paragraph under
has some inconsistencies:
Optional: Increase the frequency of queue synchronization. This only applies to configurations where server redundancy is used for high availability. Increase the client’s pool configuration, subscription-ack-interval. The client periodically sends a batch acknowledgment of messages to the server, rather than acknowledging each message individually. A lower setting speeds message delivery and generally reduces traffic between the server and client. A higher setting helps contain server queue size.
Third sentence: “Increase…subscription-ack-interval“—this seems backward to me. It certainly disagrees with the first sentence since the interval is inversely proportional to the frequency.
Fifth sentence: “…and generally reduces traffic…“—is that true? I doubt it.
Last sentence: “A higher setting helps contain server queue size.“—again backward.
