We have a microservice application, with each micro service sending events to Amplitude. All events will have a device_id, and some events will have both a device_id and a user_id in their JSON.
Let say we send 20 events to Amplitude. 10 of them have both an user_id and a device_id. 10 of them only have a device_id.
Will Amplitude automatically assign the missing user_id to events that didn’t have it? Or do we have to manage something by ourselves on Amplitude?
Thanks a lot and have a great weekend.
