如何使Cassandra节点参与多个集群？
[英]How to enable a Cassandra node to participate in multiple cluster?
问题描述
I want to use Cassandra cluster for some specific purpose across data centers. 
我想将Cassandra群集用于跨数据中心的某些特定目的。 What I want to figure out is how can I enable a single Cassandra node to participate in multiple clusters at the same time? 我想弄清楚的是，如何使单个Cassandra节点能够同时参与多个集群？ I googled it, however I could not find any use case of Cassandra as I mentioned above. 我用谷歌搜索，但是如上所述，我找不到Cassandra的任何用例。 Is this possible with the current architecture of Cassandra? 当前的Cassandra架构有可能吗？
Thanks 谢谢

You cannot do that. 你不能这样做。 By design all nodes in Cassandra cluster ate equal. 通过设计，Cassandra群集中的所有节点都相等。 I think Cassandra designers had that very goal in mind and wanted to depart from MongoDB architecture where you have several different kinds of nodes. 我认为Cassandra设计师的目标就是实现这一目标，并希望脱离拥有多种节点类型的MongoDB架构。 So, all nodes are equal, thus no way to have "special purpose" node even in a single cluster. 因此，所有节点都是相等的，因此即使在单个群集中也无法拥有“特殊目的”节点。
