Endpoint Properties

Name	Type	Required	Default	Description
`topicName`	string	✓		Topic name of this endpoint.
`namesrvAddr`	string		`localhost:9876`	Name server address of RocketMQ cluster.
`consumerGroup`	string			Consumer group name.
`subscribeTags`	string		`*`	Subscribe tags of consumer. Multiple tags could be split by , such as TagATagB
`bridgeErrorHandler`	boolean		`false`	Allows for bridging the consumer to the Camel routing Error Handler, which mean any exceptions (if possible) occurred while the Camel consumer is trying to pickup incoming messages, or the likes, will now be processed as a message and handled by the routing Error Handler. Important: This is only possible if the 3rd party component allows Camel to be alerted if an exception was thrown. Some components handle this internally only, and therefore bridgeErrorHandler is not possible. In other situations we may improve the Camel component to hook into the 3rd party component and make this possible for future releases. By default the consumer will use the org.apache.camel.spi.ExceptionHandler to deal with exceptions, that will be logged at WARN or ERROR level and ignored.
`exceptionHandler`	object			To let the consumer use a custom ExceptionHandler. Notice if the option bridgeErrorHandler is enabled then this option is not in use. By default the consumer will deal with exceptions, that will be logged at WARN or ERROR level and ignored.
`exchangePattern`	object			Sets the exchange pattern when the consumer creates an exchange.
`producerGroup`	string			Producer group name.
`replyToConsumerGroup`	string			Consumer group name used for receiving response.
`replyToTopic`	string			Topic used for receiving response when using in-out pattern.
`sendTag`	string			Each message would be sent with this tag.
`waitForSendResult`	boolean		`false`	Whether waiting for send result before routing to next endpoint.
`lazyStartProducer`	boolean		`false`	Whether the producer should be started lazy (on the first message). By starting lazy you can use this to allow CamelContext and routes to startup in situations where a producer may otherwise fail during starting and cause the route to fail being started. By deferring this startup to be lazy then the startup failure can be handled during routing messages via Camel's routing error handlers. Beware that when the first message is processed then creating and starting the producer may take a little time and prolong the total processing time of the processing.
`requestTimeoutCheckerIntervalMillis`	integer		`1000`	Check interval milliseconds of request timeout.
`requestTimeoutMillis`	integer		`10000`	Timeout milliseconds of receiving response when using in-out pattern.
`accessKey`	string			Access key for RocketMQ ACL.
`secretKey`	string			Secret key for RocketMQ ACL.
