Summarize traces to a single event #1523
Description
Is your feature request related to a problem? Please describe.
The problem with sampling based on TraceID is that sometimes traces are related.
The problem with dropping all evidence of a trace is that there may be clues about it that you'd want to keep handy.
Describe the solution you'd like
This mechanism in the pr linked below is a way to have refinery use the spans in its cache to send some record of what it saw to Honeycomb.
Describe alternatives you've considered
Session awareness seems to require buffering spans for too long.
Link awareness will end up propagating too far and keeping too many spans in some cases.
