After I modify rules in dashboard, all rules of the corresponding application are cleared. The log shows that the resource name was not received(is null) in the dynamicsentinelproperty, so the rule was rejected. I want to know where the configuration is wrong, thx
You may upgrade your fastjson dependency.

Hi 各位大佬好,sentinel 集成apollo 持久化我有一个疑问,客户端集成sentinel apollo database ,我那个客户端本身就集成了Apollo appId 为gateway ,现在我需要新创建一个apollo-sentinel ,然后客户端监听apollo-sentinel 上的变化,但是这时候项目就有两个appId 了,假如我设置了System.setProperty("app.id","apollo-sentinel") 另外一个appId gateway 可以被监听到吗?

I use sentinel to implement resiliency for by web services.
I found it is very difficult to write multiple tests for the same resource with different rules because sentinel keeps context between tests. I need to set to all counters before each test begins.
For example sentinel_block_requests_total is Not null when the second test is running or node. totalException() is not 0. Do you have APi which reset node contexts and counters ?

各位大佬,我有一个疑问,sentinel Java版里面有预热逻辑我的理解为 Java 需要启动JVM进程来运行中间代码,所以需要预热。但是 Golang 版的就直接编译为二进制可执行文件,是否还需要有预热的逻辑?

如果理解的有问题还请各位大佬指教

@taidixiong It's not planned yet. You may leverage dynamic data-source modules in Sentinel Go.

问一下,使用集群控流时,控制台中机器列表都显示健康状态,Token Server正常,但是 Token Client都处于未连接状态是什么原因呢?

确保 token server/client 分配关系正确

请问一下,对于已经发起的调用,如何在timeout之后,终止请求呢?类似hystrix那要,抛出一个HystrixTimeout异常。

目前还没有支持托管调用的超时熔断。社区可以一起讨论下方案

提个问题,将 Dashboard 改造成 Nacos 做规则持久化之后,会存在这样的问题。
比如,dashboard 部署5个节点,通过 nginx 做软负载,由于目前dashboard 每个节点会缓存一份某次查询后的最新数据。假如 node 1 先查询,node 1 本地缓存 nacos 最新的规则配置,如果当用户基于node1,查询到的结果做删除操作,此时删除的请求落在了 node2,但 node2并没要经过查询,没有这份缓存数据。 @sczyh30

发现好几个地方,在hashmap里加新值并不是直接在原来旧的map上增加,而是新生成一个map,这块是有什么考虑吗
