------------------------------------------------------------------

Sorry,
only now I verified that we can modify{{ linger.ms}} and {{batch.size}} in this way:


{code:xml}
		<Kafka name="Kafka" topic="log-collector" syncSend="false"
			batchSize="8192">
			<PatternLayout
				pattern="%d{HH:mm:ss.SSS} [%t] %-5level %logger{36} - %msg%n" />
			<Property name="bootstrap.servers">localhost:9092</Property>
			<Property name="linger.ms">30</Property>
			<Property name="batch.size">16384</Property>
		</Kafka>
{code}

I try to close this issue.

Thanks at all
