   Parameter	Description
   Maximum Retries	Maximum number of times that messages are resent upon retrieval failures. Value range: 1–16
   Broadcast	Indicates whether messages are broadcast. If this option is enabled, each message is retrieved by all consumers in the consumer group. If this option is disabled, each message is retrieved by only one consumer in the consumer group.
   Orderly	This parameter is mandatory when the RocketMQ instance version is 5.x. If this option is enabled, consumers consume messages in sequence. Orderly consumption ensures sequential consumption by message sending. In this case, earlier messages are consumed before later messages
