-----------------------------------
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.
