getAckDeadlineSeconds

public int getAckDeadlineSeconds()

 The approximate amount of time (on a best-effort basis) Pub/Sub waits for
 the subscriber to acknowledge receipt before resending the message. In the
 interval after the message is delivered and before it is acknowledged, it
 is considered to be <i>outstanding</i>. During that time period, the
 message will not be redelivered (on a best-effort basis).
 For pull subscriptions, this value is used as the initial value for the ack
 deadline. To override this value for a given message, call
 `ModifyAckDeadline` with the corresponding `ack_id` if using
 non-streaming pull or send the `ack_id` in a
 `StreamingModifyAckDeadlineRequest` if using streaming pull.
 The minimum custom deadline you can specify is 10 seconds.
 The maximum custom deadline you can specify is 600 seconds (10 minutes).
 If this parameter is 0, a default value of 10 seconds is used.
 For push delivery, this value is also used to set the request timeout for
 the call to the push endpoint.
 If the subscriber never acknowledges the message, the Pub/Sub
 system will eventually redeliver the message.
