DESCRIPTION
Updates an existing Cloud Pub/Sub subscription.
POSITIONAL ARGUMENTS
Subscription resource - Name of the subscription to update. 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.
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.
--enable-exactly-once-delivery
Whether or not to enable exactly-once delivery on the subscription. If true, Pub/Sub provides the following guarantees for the delivery of a message with a given value of message_id on this subscription: The message sent to a subscriber is guaranteed not to be resent before the message's acknowledgment deadline expires. An acknowledged message will not be resent to a subscriber. Use --no-enable-exactly-once-delivery to disable this flag.
--expiration-period=EXPIRATION_PERIOD
The subscription will expire if it is inactive for the given period. Valid values are strings of the form INTEGER[UNIT], where UNIT is one of "s", "m", "h", and "d" for seconds, minutes, hours, and days, respectively. If the unit is omitted, seconds is assumed. This flag additionally accepts the special value "never" to indicate that the subscription will never expire.
--message-retention-duration=MESSAGE_RETENTION_DURATION
How long to retain unacknowledged messages in the subscription's backlog, from the moment a message is published. If --retain-acked-messages is true, this also configures the retention of acknowledged messages. Specify "default" to use the default value of 7 days. The minimum is 10 minutes, and the maximum is 31 days. Valid values are strings of the form INTEGER[UNIT], where UNIT is one of "s", "m", "h", and "d" for seconds, minutes, hours, and days, respectively. If the unit is omitted, seconds is assumed.
--retain-acked-messages
Whether or not to retain acknowledged messages. If true, messages are not expunged from the subscription's backlog until they fall out of the --message-retention-duration window. Acknowledged messages are not retained by default. Use --no-retain-acked-messages to disable this flag.
--update-labels=[KEY=VALUE,…]
List of label KEY=VALUE pairs to update. If a label exists, its value is modified. Otherwise, a new label is created.

Keys must start with a lowercase character and contain only hyphens (-), underscores (_), lowercase characters, and numbers. Values must contain only hyphens (-), underscores (_), lowercase characters, and numbers.

When updating BigQueryConfig flags, all BigQueryConfig flags must be specified. Otherwise, any omitted BigQueryConfig flags revert to their default value.

--bigquery-table=BIGQUERY_TABLE

Whether or not to write message metadata including message ID, publish timestamp, ordering key, and attributes to BigQuery. The subscription name, message_id, and publish_time fields are put in their own columns while all other message properties other than data (for example, an ordering_key, if present) are written to a JSON object in the attributes column. Use --no-write-metadata to disable this flag.
