Elasticsearch文档指出：
快照存储库可以安全地扩展到数千个快照。但是，要管理其元数据，一个大存储库需要在主节点上更多的内存。保留规则确保存储库的元数据不会增长到可能破坏主节点稳定的大小。
什么是“安全”数量的快照不会破坏召集节点的稳定？
我正在使用8.2版，需要在我的存储库中节省1000-3000个快照，这是安全的吗？
The Elasticsearch documentation states:
A snapshot repository can safely scale to thousands of snapshots. However, to manage its metadata, a large repository requires more memory on the master node. Retention rules ensure a repository’s metadata doesn’t grow to a size that could destabilize the master node.

What is a "safe" number of snapshots that will not destabilize the muster node?
I'm using version 8.2 and need to save between 1000-3000 snapshots in my repository, is this safe?

它们不是每句话的规则，这将取决于您的用例。
但是您可以查看默认情况下设置弹性托管服务。

They are no rules per say, it will depends on you use case.
But you can look at the settings by default on elastic managed services.
But as you mentioned, if you have big master nodes you could have more.
