stack
Parameters
value
The maximum number of accounts in which to perform this operation at one time. This is dependent on the value of StackSetFailureToleranceCount . StackSetMaxConcurrentCount is at most one more than the StackSetFailureToleranceCount . Note that this setting lets you specify the maximum for operations. For large deployments, under certain circumstances the actual number of accounts acted upon concurrently may be lower due to service throttling. Applicable only to a CFN_STACKSET provisioned product type. Conditional: You must specify either StackSetMaxConcurrentCount or StackSetMaxConcurrentPercentage , but not both.
