语法

{
  "Type": "ALIYUN::SLS::ConsumerGroup",
  "Properties": {
    "ConsumerGroup": String,
    "Logstore": String,
    "Order": Boolean,

属性

属性名称	类型	必须	允许更新	描述	约束
ConsumerGroup	String	是	否	消费组名称。	在 Project 下必须唯一。
Logstore	String	是	否	Logstore 名称。	无
Order	Boolean	是	是	是否按顺序消费。	取值： true：按顺序消费。同一个 Shard 内按照保留字段__tag__:__receive_time__由小到大按顺序消费。 Shard 分裂后，先消费原 Shard 数据，然后同时消费由该 Shard 分裂的 Shard 数据。 Shard 合并后，先消费原 Shard 数据，然后消费由原 Shard 合并后的新 Shard 数据。 false：不按顺序消费。即所有 Shard 同时开始消费，Shard 分裂或者合并后产生的新 Shard，也会立即消费。
Project	String	是	否	Project 名称。	无
Timeout	Integer	是	是	超时时间。	在超时时间段内没有收到心跳，消费者将被删除。单位：秒。

返回值

Fn::GetAtt

Project：Project 名称。
Logstore：Logstore 名称。
ConsumerGroup：消费组名称。

示例

YAML

ROSTemplateFormatVersion: '2015-09-01'
Parameters:
  Order:
    Type: Boolean
    Description:
      en: |-
        Specifies whether to consume data in sequence. Valid values:
        true
        In a shard, data is consumed in ascending order based on the value of the **__tag__:__receive_time__** field.
        If a shard is split, data in the original shard is consumed first. Then, data in the new shards is consumed at the same time.
        If shards are merged, data in the original shards is consumed first. Then, data in the new shard is consumed.
        false Data in all shards is consumed at the same time. If a new shard is generated after a shard is split or after shards are merged, data in the new shard is immediately consumed.
    Required: true
  Project:
    Type: String
    Description:
      en: The name of the project.
    Required: true
  Logstore:
    Type: String
    Description:
      en: The name of the Logstore.
    Required: true
  Timeout:
    Type: Number
    Description:
      en: 'The timeout period. If the server does not receive heartbeats from a consumer within the timeout period, the server deletes the consumer. Unit: seconds.'
    Required: true
    MinValue: 1
    MaxValue: 4294967295
  ConsumerGroup:
    Type: String
    Description:
      en: The name of the consumer group. The name must be unique in a project.
    Required: true

    Type: ALIYUN::SLS::ConsumerGroup
    Properties:
      Order:
        Ref: Order
      Project:
        Ref: Project
      Logstore:
        Ref: Logstore
      Timeout:
        Ref: Timeout
      ConsumerGroup:
        Ref: ConsumerGroup
Outputs:
  Project:
    Description: The name of the project to which the logstore belongs.
    Value:
      Fn::GetAtt:
        - SLSConsumerGroup
        - Project
  Logstore:
    Description: The name of the logstore to which this consumer group belongs.
    Value:
      Fn::GetAtt:
        - SLSConsumerGroup
        - Logstore
  ConsumerGroup:
    Description: The name of the consumer group.
    Value:
      Fn::GetAtt:
