Table 1 Consumer group parameters Parameter
Description
Maximum Retries
Maximum number of times that messages are resent upon consumption failures. For example, if this parameter is set to 3, a message can be delivered for a maximum of 4 times. One time is for delivering the original message, and 3 times are for redelivery.
Value range: 1–16
Modifying this parameter takes effect only after the consumer group is restarted. To avoid infinite retries, set a proper value as required. A large value may increase the system pressure.
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
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
