如果启用保存事件，Keycloak 会给出 Lock wait timeout exceeded 错误
Keycloak giving Lock wait timeout exceeded error in case Save Events enable
我在我的项目中使用 keycloak 作为身份代理。
环境设置：
Keycloak 版本 16.1.1 部署在具有副本 2 的 k8s 集群中。
集群配置：
- name: JGROUPS_DISCOVERY_PROTOCOL
value: kubernetes.KUBE_PING
- name: KUBERNETES_NAMESPACE
valueFrom:
fieldRef:
apiVersion: v1
fieldPath: metadata.namespace
- name: CACHE_OWNERS_COUNT
value: "2"
- name: CACHE_OWNERS_AUTH_SESSIONS_COUNT
value: "2"
在 keycloak 设置中，我们想要记录登录和注销事件，所以我启用了 Save Events 并添加了如下保存类型
事件配置：
现在，当用户 login/logout 来自应用程序时，我在日志中收到以下错误并且事件未保存，我不会一直收到此错误。
错误：

如果我禁用 Save Events
，我不会收到此错误
问题出在 MariaDB Opensource 数据库上。
我用 show processlist 检查了数据库，我发现 table EVENT_ENTITY 和 table 大小上的许多删除和插入查询 运行 是大约 14GB。
我截断了 table EVENT_ENTITY，因为我不需要较旧的事件。
截断记录后一切正常。

如果我禁用 Save Events
问题出在 MariaDB Opensource 数据库上。
我用 show processlist 检查了数据库，我发现 table EVENT_ENTITY 和 table 大小上的许多删除和插入查询 运行 是大约 14GB。
我截断了 table EVENT_ENTITY，因为我不需要较旧的事件。
截断记录后一切正常。
