Still, I think it’s the right default to start with serializable. Then when you have performance issues you can think long and hard about whether relaxed isolation levels will work in a big free way. Better to start with a correct application.
replyStarting with serializable is not free, there is a coding cost to pay to handle all the concurrency errors.
replyYep. Its a wonderful capability to have for some situations, but for 90% of applications SERIALIZABLE isolation is overkill.
