Great catch! This should properly be implemented using leases: lease.acquire('count') local count = storage.count or 0 storage.count = count + 1

Great catch! This should properly be implemented using leases: lease.acquire('count') local count = storage.count or 0 storage.count = count + 1 lease.release('count') return {count=count} We skipped the lease just for simplicity's sake, but if you need that kind of protection, that's why we implemented leases.
