> The {{JobResultStore}} interface is synchronous currently. For the {{FileSystemJobResultStore}} this means that (possibly) IO-heavy operations have to be explicitly called moved to the ioExecutor within the Dispatcher.
> Instead, we could change the {{JobResultStore}} interface in a way that it returns {{CompletableFuture}} instances instead. That would enable us to run the {{FileSystemJobResultStore}} operations in the ioExecutor which would be set when initializing the {{{}FileSystemJobResultStore{}}}. This would move the responsibility of where to run the operation from the {{Dispatcher}} into the {{JobResultStore.}}
