Add option for TransactionIsolationLevel setting
danielpowell4 opened this issue · comments
First up: thanks for this awesome library. It has transformed my day-to-day in a great way!
I'm wondering if you are interested in a pull request to expose 'isloationLevel' as a setting that can be defined for transactions
As context, we're seeing some deadlocks in our growing test suites due to various tests and factories trying to create default users in our test setup. I believe that changing from the postgres default of 'Read Committed' to 'Serializable' would help us
As of a few days ago, Prisma itself merged a PR to allow these transaction options to be set on the PrismaClient
via a new transactionOptions
setting per prisma/prisma#19592
I believe it would most need to be added here with a safe default of 'undefined'
