我在同一个 L2 网络上有 12 个 Kafka 节点。
我想在同一个 L2 网络上创建 4 个 Kafka 集群(每个集群有 3 个节点)。
是否可以做到这一点以及如何做到？ 如果没有那么解决方法是什么？
最佳答案
Kafka 集群基本上是由其成员使用的 Zookeeper 数据模型定义的。因此，如果您希望某些代理属于给定集群，则必须使它们指向同一个 Zookeeper 命名空间。实际上，如果您想要有 4 个集群，那么您的 Zookeeper 集合中将需要 4 个不同的 chroot，并使每个集群使用不同的 chroot。例如，集群 A 的成员将使用 zookeeper.connect=127.0.0.1:2181/cluster/a，集群 B 的成员将使用 zookeeper.connect=127.0.0.1:2181/cluster/b等等。当然，另一种选择是为每个集群使用完全独立的 Zookeeper 集合。

An optional "chroot" suffix may also be appended to the connection string. This will run the client commands while interpreting all paths relative to this root (similar to the unix chroot command). If used the example would look like: "127.0.0.1:4545/app/a" or "127.0.0.1:3000,127.0.0.1:3001,127.0.0.1:3002/app/a" where the client would be rooted at "/app/a" and all paths would be relative to this root - ie getting/setting/etc... "/foo/bar" would result in operations being run on "/app/a/foo/bar" (from the server perspective). This feature is particularly useful in multi-tenant environments where each user of a particular ZooKeeper service could be rooted differently. This makes re-use much simpler as each user can code his/her application as if it were rooted at "/", while actual location (say /app/a) could be determined at deployment time.
