Members
executed(List)
The CommandDto#getInteractionId() interactionId s of the CommandDto s that were executed.
The commands thus identified may or may not have executed successfully; indeed if there was a deadlock then the transaction will have been rolled back and so the command may not even have been executed at all.
Implementation note: the CommandDto s are not passed in, instead only the command’s CommandDto#getInteractionId() interactionId , to avoid issues and complications with the state of the in-memory CommandDto ; is it in sync with the database if a deadlock occurred for example? Passing in just the identifier means that it’s the responsibility of the listener to determine the state, typically by refetching the CommandLogEntry (that CommandLogEntry#getCommandDto() contains the CommandDto ) in a separate transaction.
