LOG4J2-1733 Caveat in documentation about Kafka syncSend


> Add SyncSend attribute to KafkaAppender (as in KafkaLog4jAppender)
> ------------------------------------------------------------------
> 
> Key: LOG4J2-1733
> URL: https://issues.apache.org/jira/browse/LOG4J2-1733
> Project: Log4j 2
> Issue Type: Improvement
> Components: Appenders
> Affects Versions: 2.5
> Environment: Kafka 0.10.1.0
> Reporter: Vincent Tieleman
> Assignee: Mikael Ståldal
> Fix For: 2.8
> 
> 
> The KafkaLog4jAppender (shipped with Kafka and usable with log4j), has a syncsend \
> property that improves performance significantly by not blocking a send to Kafka. \
> I've tried many other configuration settings and setups, but find that none of \
> these approaches improved the logging performance to Kafka as significantly as \
> setting the syncsend property to false. Unfortunately, the syncsend property is not \
> supported by the KafkaAppender shipped with log4j2 and the KafkaLog4jAppender only \
> supports log4j, so I am stuck with forking the code and making the change myself. \
> Could you please introduce this property in the KafkaAppender in log4j2?
