❔ Best architectural design choice?
If I have multiple instances of multiple apps all working to do similar things, and they all need these "accounts" I store in a MySQL database, but only one app can have one of them at a time, and once an app has used one it can't be used again for 30 minutes after being initially used last. What is the best way to implement concurrent thread-safe access? I feel like row or table locking the database via queries would cause a lot of issues?
