Apache APISIX: supports obtaining etcd data information through plugin

Apache APISIX

Apache APISIX is a dynamic, real-time, high-performance API gateway, based on the Nginx library and etcd.

APISIX provides rich traffic management features such as load balancing, dynamic upstream, canary release, circuit breaking, authentication, observability, and more.

You can use Apache APISIX to handle traditional north-south traffic, as well as east-west traffic between services. It can also be used as a k8s ingress controller.

Background
 
When we get the stored data of etcd, we need to manually execute the URI request method to get each piece of data, and we cannot monitor the changed data in etcd. This is not friendly to issues such as obtaining multiple etcd stored data and monitoring etcd data changes. Therefore, we need to design a method to solve this problem.
