Subject [jira] [Created] (KAFKA-8505) Limit the maximum number of connections per ip client ID
Date Fri, 07 Jun 2019 13:08:00 GMT
Igor Soarez created KAFKA-8505:

             Summary: Limit the maximum number of connections per ip client ID
                 Key: KAFKA-8505
                 URL: https://issues.apache.org/jira/browse/KAFKA-8505
             Project: Kafka
          Issue Type: New Feature
            Reporter: Igor Soarez

As highlighted by KAFKA-1512 back in 2014, it is important to be able to limit the number
of client connections to brokers to maintain service availability. With multiple use-cases
on the same cluster, it's important to prevent one misconfigured use-case from affecting other

Cloud infrastructure technology has come a long way since then. Nowadays days in a private
network using container orchestration technology, IPs come cheap. Limiting connections solely
on origin IP is no longer acceptable.

Kafka needs to support connection limits based on client identity.

A new configuration property - {{max.connections.per.clientid}} - should work similarly to
{{max.connections.per.ip}} using ConnectionQuotas, managed straight after parsing the request
header in SocketServer.
