----------------------------------------
Summary: Set a default producer-window-size on cluster connection
Key: ARTEMIS-3083
URL: https://issues.apache.org/jira/browse/ARTEMIS-3083
Project: ActiveMQ Artemis
Issue Type: Improvement
Components: Broker
Reporter: Francesco Nigro
Assignee: Francesco Nigro
The current producer-window-size configuration for cluster connection is -1 ie
unbounded: it means that in case of an intermittent slow network or scarce CPU
resource on the receiving cluster node (due to GC activity, OOM or other
reasons) both brokers risk to go OOM:
* the sender one because of the resend cache on the channel of the cluster
connection: having unbounded granted credits means that it could grow unbounded
while containing the clustered packets awaiting to get response
* the receiver one because of the Actor abstraction on the cluster connection:
because the sender would try to send as much packets it can, regardless the
ability of the receiver to consume them
