NAME
    gcloud alpha pubsub subscriptions modify-ack-deadline - modifies the ACK
        deadline for a specific Cloud Pub/Sub message

SYNOPSIS
    gcloud alpha pubsub subscriptions modify-ack-deadline SUBSCRIPTION
        ([ACK_ID ...] --ack-ids=[ACK_ID,...]) --ack-deadline=ACK_DEADLINE
        [GCLOUD_WIDE_FLAG ...]

DESCRIPTION
    (ALPHA) (DEPRECATED) Modifies the ACK deadline for a specific Cloud Pub/Sub
    message.

    This command has been renamed. Please use modify-message-ack-deadline
    instead.

    This method is useful to indicate that more time is needed to process a
    message by the subscriber, or to make the message available for redelivery
    if the processing was interrupted.

POSITIONAL ARGUMENTS
     Subscription resource - Name of the subscription messages belong to. This
     represents a Cloud resource. (NOTE) Some attributes are not given
     arguments in this group but can be set in other ways.

     To set the project attribute:
      ◆ provide the argument subscription on the command line with a fully
        specified name;
      ◆ provide the argument --project on the command line;
      ◆ set the property core/project.

     This must be specified.

       SUBSCRIPTION
          ID of the subscription or fully qualified identifier for the
          subscription.

          To set the subscription attribute:
          ▸ provide the argument subscription on the command line.

     Exactly one of these must be specified:

       [ACK_ID ...]
          (DEPRECATED) One or more ACK_IDs to modify the deadline for. An
          ACK_ID is a string that is returned to subscribers
          (https://cloud.google.com/pubsub/docs/reference/rpc/google.pubsub.v1#google.pubsub.v1.ReceivedMessage).
          along with the message. The ACK_ID is different from the message ID
          (https://cloud.google.com/pubsub/docs/reference/rpc/google.pubsub.v1#google.pubsub.v1.PubsubMessage).

          Positional argument ACK_ID is deprecated. Please use --ack-ids
          instead.

       --ack-ids=[ACK_ID,...]
          One or more ACK_IDs to modify the deadline for. An ACK_ID is a string
          that is returned to subscribers
          (https://cloud.google.com/pubsub/docs/reference/rpc/google.pubsub.v1#google.pubsub.v1.ReceivedMessage).
          along with the message. The ACK_ID is different from the message ID
          (https://cloud.google.com/pubsub/docs/reference/rpc/google.pubsub.v1#google.pubsub.v1.PubsubMessage).

REQUIRED FLAGS
     --ack-deadline=ACK_DEADLINE
        The number of seconds the system will wait for a subscriber to
        acknowledge receiving a message before re-attempting delivery.

GCLOUD WIDE FLAGS
    These flags are available to all commands: --access-token-file, --account,
    --billing-project, --configuration, --flags-file, --flatten, --format,
    --help, --impersonate-service-account, --log-http, --project, --quiet,
    --trace-token, --user-output-enabled, --verbosity.

    Run $ gcloud help for details.

NOTES
    This command is currently in alpha and might change without notice. If this
    command fails with API permission errors despite specifying the correct
    project, you might be trying to access an API with an invitation-only early
    access allowlist. This variant is also available:

        $ gcloud beta pubsub subscriptions modify-ack-deadline
