Kafka 中的 Zoopekeeper 实例 [英] Zoopekeeper instances in Kafka

问题描述

我有 3 个安装了 Kafka 的节点.所有这 3 个节点都有自己的 zookeeper 实例.需要 3 个 zookeeper 实例还是 1 个 zookeeper 实例就足够了?我们是否应该有多个 Zookeeper 实例来实现容错?在这种情况下，其中一个实例会作为主实例，其他实例会是副本吗?

I have 3 nodes where Kafka is installed. All these 3 nodes have their own zookeeper instances. Are 3 zookeeper instances required or is 1 zookeeper instance suffice? Should we have multiple zookeeper instances for fault tolerance & in such a scenario would one of the instances act as primary and would others be replica?

推荐答案

我不确定所有这 3 个节点都有自己的zookeeper 实例"是什么意思基本上你应该有一个一个、三个或五个 Zookeeper 实例的集群和所有 Kafka 代理应该使用相同的集群.您不需要超过一个 Zookeeper 实例，但由于可用性，我强烈建议使用三个或五个实例.我们使用三个 Zookeeper 实例来运行我们的 Kafka 集群.

I'm not sure what you mean by "All these 3 nodes have their own zookeeper instances" Basically you should have a single cluster of one, three or five Zookeeper instances and all Kafka brokers should use the same cluster. You don't need more than one Zookeeper instance but I'd highly recommend to use three or five instances because of availability. We use three instances of Zookeeper to run our Kafka cluster.
