How will the data accumulate in the persistent queue of the universal forwarder?

i have 1 universal forwarder and 2 heavy forwarder.
If two of my heavy forwarder lost communication with the UF at the same time, how will the data accumulate in the persistent queue of the UF? 
 
please provide splunk documentation or previous splunk community Q&A if you have any.

i installed  a universal forwarder in Windows server 2019.
assume i configured for 2 heavy forwarder and persistent queue is 10 GB. Does that mean i'll get 20 GB for 2 heavy forwarder or 10 GB for 2 forwarder ?
where and how can i check my persistent queue, whether the data is storing or not ?

Hi @human96 

Just one thing to highlight
Persistent queuies are not avaiable to all inputs ex: file monitoring , 

it only works with follwing inputs

and regarding your question for queue size  

it would be 10 GB for all, it doesnt depend on forwarder count
