maxConcurrentPercentage property
The maximum percentage of accounts in which to perform this operation at one time.
When calculating the number of accounts based on the specified percentage, AWS CloudFormation rounds down to the next whole number. This is true except in cases where rounding down would result is zero. In this case, CloudFormation sets the number as one instead.
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.
Conditional: You must specify either MaxConcurrentCount or
MaxConcurrentPercentage, but not both.
