re: Making mistakes: My first big programming blunder VIEW POST


Pushed a job queue in production that sent a 1-time email to customers greeting them on the next day after they made an account.

The job-pushing code was configured to run once per hour, picking new accounts from the DB and sending the emails.

I mismatched transactional/non-transactional, and we got emails going about 24 times a day for most customers, and lots of complaints.
