massakam opened a new pull request #4765: [Issue #4756][broker] Process requests asynchronously on some REST APIs (1)
URL: https://github.com/apache/pulsar/pull/4765
 
 
   Master Issue: #4756
   
   ### Motivation
   
   Some of the REST APIs provided by broker send HTTP request to oneself internally using a PulsarAdmin instance when they receive requests from clients. This may cause a deadlock, as the pulsar-web thread is blocked until a response from oneself is returned. As with https://github.com/apache/pulsar/pull/4487, these APIs should be introduced async rest handlers.
   
   ### Modifications
   
   In this pull-request, added async rest handlers to the following tow APIs for non-persistent topics.
   ```
   /admin/non-persistent/{tenant}/{cluster}/{namespace}
   /admin/v2/non-persistent/{tenant}/{namespace}
   ```
   I intend to fix other APIs in subsequent pull-requests.
   
   ### Verifying this change
