Migrating bajillions of database records at Stripe
What database are they using?  Their description reads like they used some NoSQL database, and then they needed to do an ALTER TABLE.Also, how many merchants can they have?  I have a database of all US businesses on a desktop machine and a server.  It's a few gigabytes.  There are about 20 million business entities in the US, and some of them may not be Stripe customers.
