alt Hacker NewsAgree, even in the payments space usage-billing metrics providers like Chargebee / Lago etc get order(s) of magnitude more data than payment.
Granted payments and associated ledges require a level of consistency that other systems do not require, but that is orthogonal to high volume.
Stripe also supports usage based billing... If you think Lago gets more volume than Stripe I just don't know what to tell you lol
