Isn't it OK to do I/O in a transaction as long as doing

Isn't it
If you want to do I/O from a transaction, just use an agent to do the
I/O. Since the agent is only sent off at commit, you don't have to
worry about retries. This doesn't answer your questions about
idempotent I/O, but I think it is a strategy that you can use.
