Path Parameters

organizationId · string<uuid> · required

ID of the organization that owns the service.

serviceId · string<uuid> · required

ID of the service to update scaling parameters.

Body

application/json

minReplicaMemoryGb · number

Minimum auto-scaling memory in Gb for a single replica. Available only for 'production' services. Must be a multiple of 4 and greater than or equal to 8.

Required range: 8 <= x <= 356Must be a multiple of 4

Example:

16

maxReplicaMemoryGb · number

Maximum auto-scaling memory in Gb for a single replica . Available only for 'production' services. Must be a multiple of 4 and lower than or equal to 120 for non paid services or 356 for paid services.

Required range: 8 <= x <= 356Must be a multiple of 4

Example:

120

numReplicas · number

Number of replicas for the service. The number of replicas must be between 2 and 20 for the first service in a warehouse. Services that are created in an existing warehouse can have a number of replicas as low as 1. Further restrictions may apply based on your organization's tier. It defaults to 1 for the BASIC tier and 3 for the SCALE and ENTERPRISE tiers.

Required range: 1 <= x <= 20

Example:

3

idleScaling · boolean

When set to true the service is allowed to scale down to zero when idle. True by default.
