Two database design choices:
- Each server gets its own quotes and saves all its own data
- Need to read user id from each request and send each user to a predetermined server
- Need multiple Etrade accounts, one for each server, unless we get a deal with Etrade
- Switch to a distributed database with master-master replication
- A lot of work
- Might kill sub-second performance? Might not. We already have delayed-write.
