Fascinating. How does it handle very large repos and binary files? I want petabyte scale history and terabyte scale sparse clones. Alternatively, why use this

Fascinating. How does it handle very large repos and binary files? I want petabyte scale history and terabyte scale sparse clones. Alternatively, why use this over Git? I read the differences but feel like I’m missing a higher level difference. What problems does this solve that Git/Hg don’t solve already? What was the inspiration for starting the project?
