推荐答案
很久以前，Couchbase工程师打算建立一种概念，即具有类似于zfs池的池，但适用于分布式数据库.该功能还没有结束，但与需要添加的其他数据库功能相比，却从未引起太多关注.最终发生的事情是，池/默认池最终成为了工程师将来想要构建的东西的占位符.过去的想法是，池将是分配给集群中节点子集的存储桶的子集，这将有助于大型集群(100多个节点)的管理.
A long time ago the Couchbase engineers intended to build out a concept of having pools similar to zfs pools, but for a distributed database. The feature isn't dead, but just never got much attention compared to other database features that needed to be added. What ended up happening was that the pools/default just ended up being a placeholder for something that the engineers wanted to build in the future. In the old days the idea was that a pool would be a subset of buckets that was assigned to a subset of nodes in the cluster and that this would help with management of large clusters (100+ nodes).
现在，我要说的是不要担心整个池的概念，因为在当前(2.x版本)中，这是一个占位符，没有任何特殊含义.将来，虽然池概念可能会具有某种功能，并且将有据可查.另请注意，尚未决定Couchbase将对池执行什么操作，它们将如何工作或何时实施.这篇文章仅是为了提供池概念存在的历史.
So right now I would say don't worry about the whole pools concept because in the current (2.x releases) this is a placeholder that doesn't have any special meaning. In the future though there will likely be a feature around the pools concept and it will be well documented. Please also note that no decisions have been made about what Couchbase will do with pools, how exactly they will work, or when they will be implemented. This post is only meant to give the history for why the pools concept exists.
