I have a service worker up and running in my ASP.NET Core 2.2 app. I am exposed to a problem that I want to solve which is to create a fault-tolerant background service.
I have a shared table on which two different jobs select and update data. Basically what we are doing is that we are syncing Office Calendar and Mail so the token has to be stored in the database. If any of the services fails to access the API they refresh access by using refresh token and then updates it in the database as well. Now there might be a situation that one of the services is working on the same row while other has updated the tokens in the database and we might end up in an infinite loop and both update the tokens over and over again. What should be the workaround to avoid such scenarios?
Thanks
