Event-Based Architectures: The Hard Parts

To build more responsive applications, we've seen a huge shift in the past decade to event-based architectures. While they are the right tool for the job, these architectures are not without their own unique challenges. Are parallel batch systems still necessary? What techniques do you use for joining event streams with metadata? Or joining streams when they are eventually consistent? Are data migrations still an issue? How do you handle event-based transactions? Do you use a general-purpose event-based or streaming toolkit, or are they all vendor-specific?
