getMaxDeliveryAttempts()

public abstract int getMaxDeliveryAttempts()

The maximum number of delivery attempts for any message. The value must be between 5 and 100. The number of delivery attempts is defined as 1 + (the sum of number of NACKs and number of times the acknowledgement deadline has been exceeded for the message). A NACK is any call to ModifyAckDeadline with a 0 deadline. Note that client libraries may automatically extend ack_deadlines. This field will be honored on a best effort basis. If this parameter is 0, a default value of 5 is used.

int32 max_delivery_attempts = 2;

Returns
TypeDescription
int

The maxDeliveryAttempts.
