Request syntax

aliyunlog log create_consumer_group --project=<value> --logstore=<value> --consumer_group=<value> --timeout=<value> [--in_order=<value>] [--access-id=<value>] [--access-key=<value>] [--sts-token=<value>] [--region-endpoint=<value>] [--client-name=<value>] [--jmes-filter=<value>] [--format-output=<value>] [--decode-output=<value>]

Request parameters

The following table describes the required and specific parameters of the create_consumer_group command.
Parameter Type Required Example Description
--project String Yes aliyun-test-project The name of the project.
--logstore String Yes logstore-a The name of the Logstore.
--consumer_group String Yes consumer-group-1 The name of the consumer group. The name must be unique in a project.
--timeout Integer Yes 300 The timeout period. Unit: seconds.

The consumer sends heartbeats to Log Service at a regular interval to establish a connection. If Log Service does not receive the heartbeats sent by the consumer within the timeout period, Log Service releases the resources that are occupied by the consumer.

--in_order Boolean No true Specifies whether to consume data in sequence from a shard. Valid values:
  • true: The data in a shard is consumed in sequence. If the shard is split, the data in the original shard is consumed first. Then, the data in the new shards is consumed at the same time.
  • false (default value): The data in a shard is randomly consumed.
For information about the global parameters of the Log Service command-line interface (CLI), see Global variables.
