- AvailableProvisionedConcurrentExecutions
The amount of provisioned concurrency available.
Type: Integer
Valid Range: Minimum value of 0.
- LastModified
The date and time that a user last updated the configuration, inISO 8601 format.
Type: String
- RequestedProvisionedConcurrentExecutions
The amount of provisioned concurrency requested.
Type: Integer
