[jira] [Created] (KAFKA-17875) Aligh KRaft controller count recommendations

Mickael Maison created KAFKA-17875:
--------------------------------------

             Summary: Aligh KRaft controller count recommendations
                 Key: KAFKA-17875
                 URL: https://issues.apache.org/jira/browse/KAFKA-17875
             Project: Kafka
          Issue Type: Improvement
          Components: docs, kraft
            Reporter: Mickael Maison


In https://kafka.apache.org/documentation/#kraft_deployment we strongly suggest using no more than 3 controllers. This recommendation holds until we complete the implementation of [KIP-996|https://cwiki.apache.org/confluence/display/KAFKA/KIP-996%3A+Pre-Vote].

However just a few [paragraphs above|https://kafka.apache.org/documentation/#kraft_voter] we mention users typically pick between 3 and 5 controllers.

Until KIP-966 is implemented, we probably only should mention 3 controllers.
