Hello. We are currently upgrading from Prometheus old client 0.x to 1.x.
In the previous version, when using ExemplarSampler and Exemplar, the structure allowed us to include separate custom metadata, so in our system we used one additional identifier for management purposes.
However, while reviewing the 1.x version during the upgrade, it appears that the SpanContext and Exemplar classes only provide trace_id and span_id as identifiers, and do not seem to allow adding separate custom metadata. It is possible that I may have missed an extension point.
Is there any way to include a separate custom metadata identifier when using Exemplars?
