Summary of changes
The current event-formation component creates a new thread to produce each outgoing message resulting in the overhead associated with thread for each message. In this PR, the component creates a single persistent thread for producing messages to Kafka, and transfers processed traces from the main thread to this thread via a channel.
Instruction for review/testing
Commentary on the new architecture is welcome. Is this a good change?
General code review.
Has been tested on simulated and Kafka data.
