Properties

Property Type Required Editable Description Constraint
OrderType String No Yes The type of the order that you want to place. Valid values:
  • BUY: You place the order to purchase an instance.
  • UPGRADE: You place the order to upgrade the specifications of the instance.
  • DOWNGRADE: You place the order to downgrade the specifications of the instance.
ZoneId String No Yes The ID of the zone. You can call the DescribeZones operation to query the most recent zone list.
ResourceGroupId String No Yes The ID of the resource group. None.
InstanceId String No Yes The ID of the instance. This property is required if you set the OrderType property to UPGRADE or RENEW.
InstanceChargeType String No Yes The billing method of the instance. Default value: PostPaid. Valid values:
  • PrePaid: subscription
  • PostPaid: pay-as-you-go
NodeId String No Yes The ID of the data node. You can call the DescribeLogicInstanceTopology operation to query data node IDs.
Note This property takes effect if you specify the InstanceId property and the instance that you specify is a cluster instance or a read/write splitting instance.
ProductType String No Yes The edition or series of the instances. Valid values:
  • Local: Community Edition instances that use local disks or Enhanced Edition (Tair) performance-enhanced instances that use local disks
  • Tair_rdb: Tair performance-enhanced instances that use cloud disks
  • Tair_scm: Tair persistent memory-optimized instances
  • Tair_essd: Tair storage-optimized instances
  • OnECS: Community Edition instances that use cloud disks
AcceptLanguage String No Yes The language of the return values. Valid values:
  • zh-CN: Chinese
  • en-US: English
Engine String No Yes The engine type of the instance. Valid values:
  • Redis
  • Memcache

Return values (Fn::GetAtt)

  • InstanceClassIds: the IDs of the instance types.
  • InstanceClasses: details of the instance types.
Property Type Description Constraint
InstanceClassIds List The IDs of the instance types. None.
InstanceClasses List Details of the instance types. None.
ZoneId String The ID of the zone. None.
InstanceClass String The type of the instance. None.
SupportedNodeType List The type of the node. Valid values:
  • single: a master node
  • double: master and replica nodes
ShardNumber String The number of shards. None.
Architecture String The architecture of the instance. Valid values:
  • standard: standard architecture
  • cluster: cluster architecture
  • rwsplit: read/write splitting architecture
Version String The engine version of the instance. None.
SeriesType String The series of the instance. Valid values:
  • enhanced_performance_type: performance-enhanced instance
  • hybrid_storage: hybrid-storage instance
EditionType String The edition of the instance. Valid values:
  • Community: Community Edition
  • Enterprise: Enhanced Edition (Tair)
