[GitHub] [apisix] linxinshuo opened a new issue #2680: bug:config_etcd did not handle the watcher be canceled

linxinshuo opened a new issue #2680:
URL: https://github.com/apache/apisix/issues/2680


   ### Issue description
   Current version, the config_etcd watch different prefixes and maintain revisions separately, when some prefix be modified, the others can not perceive revision change. If etcd enable auto compacted,  the watcher with old revision will be canceled because revision be compacted.
   hope the watcher can handle the canceled result,  re-pull the latest revision and re-watch
   
   In current version(2.0), canceled response will case panic
