I got what you mean. The fact that the problem was an trouble. And I now use a
async process to transfer uri template. There is no other way.

>> 我最近阅读了skywalking-kong的源码，发现在记录request_url的时候，是直接记录的ngx.var.uri，这会导致url中携带动态参数，后面的系统会因为有了这个动态参数，而不进行模板化吧(记着之前听说过有这个机制)。这样就会导致系统存储的endpoint翻很多很多倍，如果打开了endpoint_alarm的话，那内存溢出估计会发生在skywalking启动的几分钟之内。这个问题开发团队有过专门的处理么？
