Compiling takes nearly 200GB of space

Hi,
I am researching on the browser fingerprinting and trying to conduct a measurement study. I need to compile the brave browser code for this. I tried it on MAC OS Catalina and it took almost 200GB of my disc space which I unfortunately ran out of. Is it normal for the code to take that much of my resource ? I understand that during compilation, chromium core as well as brave cores are downloaded but its really huge. Can you please suggest a way around?
Also, is there a proper README file on how to use sccache ?
