Hi all,
I read a few threads about the generation of a GUID (e.g. this one). My question is more about the real uniqueness a generated GUID is supposed to have.
I mean, if hundreds or thousands of users activate a given app at the same time would the inherent ability of the random generator still guarantee uniqueness? Is there any indication on a threshold where this is believed to fail?
Should I deploy a protocol where, upon an eventual duplicate is received by the server, a message is sent to the app causing a new GUID generation and so on until a unique one is received?
Should I evaluate the introduction of a "chaos generation" mechanism like randomly moving a finger on a pad as a way to strengthen the uniqueness?
I need real uniqueness (multiplatform) on a potentially large number of installations. GUID will be used to send strictly private FCM/MQTT messages.
TIA
