With this changeset, we provide an implementation for a transaction
event API. The goal is to support the emission of events with
transactions and sub-transactions, allowing a process post events that
may be rolled back later due to an error in the entire process. When
journaled, a consumer will be able to commit and rollback with the same
behavior as the producer.
Events are left to full definition by each component. We may require
more structure in the future to ensure consistency but we need more use
case before making decisions in that direction.
Events may be organized by a topic. A topic defines a single stream of
messages, that could be associated with a specific component. The topic
defines a grouped stream that may be compacted as one.
Only the contextual API is implemented here. After using, we will make a
determination to see how useful this across the board.
