我们最近将弹性云部署从6.8.5升级到了7.9，升级后我们不时会看到以下错误。
{

}此部署仅包含一个具有1g内存的节点。我们想知道这个错误的原因。是因为升级吗？
谢谢您。

首先，断路器是一种保护，某些请求不会将您的集群推到它所能处理的极限之上——这是杀死单个请求，而不是（可能）整个集群。还请注意，仅此http请求并不太大，但它会使
parent断路器- 所以这个要求再加上其他要求就太多了。最初的断路器在6.2.0中已经添加，但在7.0.0中进一步拧紧。我想这就是为什么你现在看到这个（更频繁）的原因。
你可以改变主意
indices.breaker.total.limit，但这并不是从集群中获取更多信息的神奇开关。1gb的内存可能不足以满足您的需要。
