google cloud messaging - Message throttling in GCM / FCM push notification

Question

I would like to know what is called Message throttling in Google FCM push notification? I am trying to implement a sample push notification using FCM, but didn't understand about message throttling mentioned in their steps. There is no documentation also found about it.

Could someone clarify about this term?
