Locking to avoid multiple like resources being created concurrently?

Handing Resource Count?

It will happen in parallel unless the ‘parallelism’ setting in Terraform is set to ‘1’ (it defaults to ‘10’). If the API operations to your IPAM are not atomic, then you’ll probably have to implement some sort of synchronization inside the provider to ensure that there is only one request active at a time. A sync.Mutex would be straightforward to use for this.
