backOffMaxRetries N The maximum number of retries to process the message before returning an error. Defaults to "0" which means the component will not retry processing the message. "-1" will retry indefinitely until the message is processed or the application is shutdown. And positive number is treated as the maximum retry count. The component will wait 5 seconds between retries. "3"

创建Hazelcast 实例


你可以使用Docker在本地运行Hazelcast：

docker run -e JAVA_OPTS="-Dhazelcast.local.publicAddress=127.0.0.1:5701" -p 5701:5701 hazelcast/hazelcast

然后你可以通过127.0.0.1:5701与服务器交互。


在Kubernetes上安装Hazelcast的最简单方法是使用Helm chart。
