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.
