Daniel Qian created KAFKA-6620: ---------------------------------- Summary: Documentation about "exactly_once" doesn't mention "transaction.state.log.min.isr" Key: KAFKA-6620 URL: https://issues.apache.org/jira/browse/KAFKA-6620 Project: Kafka Issue Type: Bug Components: documentation, streams Reporter: Daniel Qian
Documentation about "processing.guarantee" says: {quote}The processing guarantee that should be used. Possible values are {{at_least_once}}(default) and {{exactly_once}}. Note that exactly-once processing requires a cluster of at least three brokers by default what is the recommended setting for production; *for development you can change this, by adjusting broker setting* `{color:#FF0000}*transaction.state.log.replication.factor*{color}` {quote} If one only set *transaction.state.log.replication.factor=1* but leave *transaction.state.log.min.isr* with default value (which is 2) the Streams Application will break. Hope you guys modify the doc, thanks. -- This message was sent by Atlassian JIRA (v7.6.3#76005)
