   This is not entirely true.  If an error occurs, it is logged.
   
   The reason for this change:
   
   1) Currently, all cleanup operations of external resources used by a Pulsar Function is best effort.  There is no guarantee a resource like subscription or table will be cleanup.  We make a best effort but there is no guarantee.  Thus, this change does not really change any guarantees from that perspective.  We will be looking into ways to improve that in the future.
   
   2) Since our current model is best effort, there is no need to wait for the table deletion operation to complete.  Even though this is not an issue for Pulsar Functions, the state store client has some issues that we are investigating with cause it to block indefinitely. Thus, another reason to not to wait and be blocked forever with making any progress.
