代码：306DB::Exception：从本地主机接收到：9000 DB::Exception: 堆栈大小太大堆栈地址

如何解决代码：306DB::Exception：从本地主机接收到：9000 DB::Exception: 堆栈大小太大堆栈地址

尝试在 k8s 上部署 clickhouse 以用作石墨后端。 Clickhouse 的新手我已经浏览了具有相同问题的链接，但没有一个对我有帮助。尝试创建两台 clickhouse 服务器，计划在未来再添加一台。clickhouse 服务器部署为 k8 statefulset。

解决方法

您进行了无限循环：

CREATE TABLE IF NOT EXISTS default.graphite (
) ENGINE = Distributed('graphite','',graphite,xxHash64(Path));

分布式表指向自身。

必须是分布式的('graphite','SOMEDATABASE'

或者应该使用 remote_servers 中的默认数据库

<replica>
        <default_database>

！！！！！！ 永远不要使用循环复制
