Hi all, I’m proposing a new KIP for enabling the strongest delivery guarantee by default. Today Kafka support EOS and N-1 concurrent failure tolerance but the default settings haven’t bring them out of the box. The proposal changes include the producer defaults change to `ack=all` and `enable.idempotence=true`. Also, the ACL operation type IDEMPOTENCE_WRITE will be deprecated. If a producer has WRITE permission to any topic, it will be able to request a producer id and perform idempotent produce.

Thanks - Cheng Tan
