REQUIRED ResourceId => Str

The identifier of the resource associated with the scaling activity. This string consists of the resource type and unique identifier.

• ECS service - The resource type is "service" and the unique identifier is the cluster name and service name. Example: "service/default/sample-webapp".
• Spot Fleet request - The resource type is "spot-fleet-request" and the unique identifier is the Spot Fleet request ID. Example: "spot-fleet-request/sfr-73fbd2ce-aa30-494c-8788-1cee4EXAMPLE".
• EMR cluster - The resource type is "instancegroup" and the unique identifier is the cluster ID and instance group ID. Example: "instancegroup/j-2EEZNYKUA1NTV/ig-1791Y4E1L8YI0".
• AppStream 2.0 fleet - The resource type is "fleet" and the unique identifier is the fleet name. Example: "fleet/sample-fleet".

The unique identifier is defined by the service provider. More information is available in our GitHub repository (https://github.com/aws/aws-auto-scaling-custom-resource).
• Amazon Comprehend document classification endpoint - The resource type and unique identifier are specified using the endpoint ARN. Example: "arn:aws:comprehend:us-west-2:123456789012:document-classifier-endpoint/EXAMPLE".
• Amazon Comprehend entity recognizer endpoint - The resource type and unique identifier are specified using the endpoint ARN. Example: "arn:aws:comprehend:us-west-2:123456789012:entity-recognizer-endpoint/EXAMPLE".
• Lambda provisioned concurrency - The resource type is "function" and the unique identifier is the function name with a function version or alias name suffix that is not $LATEST. Example: "function:my-function:prod" or "function:my-function:1".
• Amazon Keyspaces table - The resource type is "table" and the unique identifier is the table name. Example: "keyspace/mykeyspace/table/mytable".
• Amazon MSK cluster - The resource type and unique identifier are specified using the cluster ARN. Example: "arn:aws:kafka:us-east-1:123456789012:cluster/demo-cluster-1/6357e0b2-0e6a-4b86-a0b4-70df934c2e31-5".
