             Summary: tuning advice for subscription-ack-interval has multiple problems
                 Key: GEODE-6585
                 URL: https://issues.apache.org/jira/browse/GEODE-6585
             Project: Geode
          Issue Type: Bug
          Components: docs
            Reporter: Bill Burcham


On this page:

[https://gemfire.docs.pivotal.io/97/geode/developing/events/limit_server_subscription_queue_size.html]

the first paragraph under
{code:java}
subscription-ack-interval{code}
has some inconsistencies:
{quote}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.
{quote}
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.
