Not sure if this make sense, but maybe would be nice to have a kind of "flag" available within the code that tells me if I'm running in a "normal" situation or during a recovery. To better explain this, let's consider the following scenario: I am processing data, let's say from a Kafka streaming, and I am updating a database based on the computations. During the recovery I don't want to update again the database (for many reasons, let's just assume that) but I want my system to be in the same status as before, thus I would like to know if my code is running for the first time or during a recovery so I can avoid to update the database again. More generally I want to know this in case I'm interacting with external entities.
