- OPTIONAL 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_idon 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. --enable-message-ordering- Whether to receive messages with the same ordering key in order. If set, messages with the same ordering key are sent to subscribers in the order that Pub/Sub receives them. Use --no-enable-message-ordering 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.
--labels=[KEY=VALUE,…]-
List of label KEY=VALUE pairs to add.
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. --message-filter=MESSAGE_FILTER- Expression to filter messages. If set, Pub/Sub only delivers the messages that match the filter. The expression must be a non-empty string in the Pub/Sub filtering language.
--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. The default value is 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.

At most one of these can be specified:
-
BigQuery Config Options. The Cloud Pub/Sub service account associated with the
enclosing subscription's parent project (i.e.,

permission to write to this BigQuery table.
--bigquery-table=BIGQUERY_TABLE-

--write-metadata- 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.
-
At most one of these can be specified:
--use-table-schema- Whether or not to use the BigQuery table schema when writing messages to BigQuery. Use --no-use-table-schema to disable this flag.
--use-topic-schema- Whether or not to use the schema for the subscription's topic (if it exists) when writing messages to BigQuery. If --drop-unknown-fields is not set, then the BigQuery schema must contain all fields that are present in the topic schema. Use --no-use-topic-schema to disable this flag.

--cloud-storage-write-metadata- Whether or not to write the subscription name, message_id, publish_time, attributes, and ordering_key as additional fields in the output. The subscription name, message_id, and publish_time fields are put in their own fields while all other message properties other than data (for example, an ordering_key, if present) are added as entries in the attributes map.
