How to limit the message publish rate for individual user

[ansari mustafa]

Hi Team,

I am using the vernemq. To authenticate users I have configured the postgres database.

in the publish_acl column I have three parameter like below.

eg: - {

          "pattern": "some/topic"

         "max_qos": 1,

         "max_payload_size": 1024

         }

is there any way I can declare the message publish rate for so that my system should not break.
