CTA Pro Tip Number 6
Today's tip is around Integration. Salesforce has their buzzwords (RPI-Request-Reply, RPI-Fire&Forget, Batch Data Sync) which are obviously great to know and good to put down in your answer. But, behind this you really need to have a solid and practical understanding of how an integration flow would work. Lets take an example. If you are going to synchronize a change to an Account record from Salesforce to SAP, how exactly would you do it? How would you notify middleware of the change? What would you do in the event of an error occuring? Would you block edits to the record whilst a sync is in progress? Think about these things and have a solid flow and approach in your CTA toolkit before appearing for the board.
Typically synchronous calls would be short-lived (default 10 secs for a callout in salesforce). Blocking an update while sync call is happening might be super important for mission-critical apps and most other apps should be fine with transaction isolation levels set up by salesforce database servers. Have you come across "blocking an update" scenarios very often?
