[GitHub] [pulsar] merajblueshift opened a new issue #9441: Creating subscription on a Topic via REST API sets the cursor to earliest position

[GitBox]

merajblueshift opened a new issue #9441:
URL: https://github.com/apache/pulsar/issues/9441


   **Describe the bug**
   When creating a subscription using REST API on an existing topic having a 
good flow of messages, the cursor is set to the earliest position and if the 
same is done via pulsar-admin it sets the cursor correctly.
   
   **To Reproduce**
   Steps to reproduce the behavior:
   1. Create a topic having messages flowing in continuously and create a 
consumer for it.
   2. Let some messages get accumulated.
   3. Create a new subscription via REST API using this REST API
       ```
       curl -X PUT -L 
http://<pulsar_url>:8080/admin/v2/persistent/<tenant>/<namespace>/<topic>/subscription/<subscription_name>_rest_api
 -H 'Content-Type: application/json' -d '{
     "messageId": "latest"
   }'
       ```
   4. Also create a subscription using Admin API
       ```
       pulsar-admin topics create-subscription -m latest -s 
<subscription_name>_admin_api persistent://<tenant>/<namespace>/<topic>
       ```
   
   **Expected behavior**
   The subscription created via REST API should also have the cursor set on the 
latest.
   
   **Screenshots**
   Both subscription_adminApi and subscription_restApi were created at the same 
time. See the difference in backlog.
