Open Pipeline Question - Span to metric

[GregOReilly]

Use Case: cut metrics from spans over a longer period of time. 

Today spans are only stored for 10 days by default. I want to extract metrics from span attribute data over a longer period of time.

Has anyone managed to do this?

I've been doing this for quite some time. Do you have a specific question you'd like an answer to?
