Shubham Raj created KAFKA-18762: ----------------------------------- Summary: 'Acks=all' not working correctly in Kafka Kraft mode. Key: KAFKA-18762 URL: https://issues.apache.org/jira/browse/KAFKA-18762 Project: Kafka Issue Type: Bug Components: kraft Affects Versions: 3.9.0 Reporter: Shubham Raj
In Kraft mode, producers are able to produce messages to a topic with a replication factor of 1, even when the {{min.insync.replicas}} setting is 2 and {{{}acks=all{}}}. This behavior is inconsistent with Zookeeper mode, where the production fails with a timeout exception as expected. This was observed in Kafka 3.9.0. We tried both Java and Python API. *Steps to Reproduce:* # Set up a Kafka cluster in Kraft mode. # Create a topic with the following properties: ** Replication Factor: 1 ** Partitions: 1 (for simplicity) # Set the {{min.insync.replicas}} configuration for the cluster to 2. # Configure a Kafka producer with {{{}acks=all{}}}. # Attempt to produce messages to the topic. -- This message was sent by Atlassian Jira (v8.20.10#820010)
