The Readme talks about a bank account.
How would transactional update look?
If I want to transfer $20 from user A to user B, the following four things need to happen transactionally:
- make sure user A has the necessary funds (reserve)
- put money into user B account (debit)
- take money from user A account (credit)
- commit
At the same time, nobody else must make an operation where they see partial results, and we can't let two operations reserve the same funds in parallel.
I don't see how this use case is supported, but that may just be because I don't know where to look?
