maxInstanceCount
integer
The limit on the maximum number of function instances that may coexist at a given time.
In some cases, such as rapid traffic surges, Cloud Functions may, for a short period of time, create more instances than the specified max instances limit. If your function cannot tolerate this temporary behavior, you may want to factor in a safety margin and set a lower max instances value than your function can tolerate.
See the Max Instances Guide for more details.
minInstanceCount
integer
The limit on the minimum number of function instances that may coexist at a given time.
Function instances are kept in idle state for a short period after they finished executing the request to reduce cold start time for subsequent requests. Setting a minimum instance count will ensure that the given number of instances are kept running in idle state always. This can help with cold start times when jump in incoming request count occurs after the idle instance would have been stopped in the default case.
