[GitHub] [apisix] gxthrj opened a new issue #4276: discuss: Suggest to add a downgrade strategy to the chash load balancing strategy

gxthrj opened a new issue #4276:
URL: https://github.com/apache/apisix/issues/4276


   ### Issue description
   
   Now when upstream chooses chash load balancing, and specify the key, such as
   
   ```yaml
     loadbalancer:
       type: chash
       hashOn: cookie
       key: "X-Foo"
   ```
   
   If the request does not contain any cookies, all traffic will visit a single node and will not be sent to other nodes.
   
   In such a scenario, downgrading the load balancing strategy to polling seems to be a more reasonable solution.
   
   What do you think?

   Already have.

   > If the specified hash_on and key can not fetch values, it will be fetch remote_addr by default.

   is a good way to go.
   I think we can also specify a fallback key, which is defined as a key that must exist in the request, such as ip, etc. 
   When the `hashOn` key does not exist, the fallback key is used.

   I think fallback strategy is required, or malicious users can leverage this drawback and send deliberated requests, which makes one of the backend endpoints under high overhead.
