为什么我们需要Solrcloud的外部动物园管理员？

Question

我想使用3台不同的机器设置solr云。我遇到的所有例子都建议我下载zookeeper。

然而，Solr带有一个内置的Zookeeper。为什么我们不能使用它？

Answer 1

Right now the embedded zookeeper is supposed to be mostly for testing/developing. Reasons being that it is less battle tested in production and that if Solr process goes down, zk goes down too, making the cluster less resilient than a separate process.

That being said, there are some voices saying that setting up a separate zk ensemble is too troublesome, so maybe this changes in the future.
