Hello, I am created a new thread for this updated document, I will finalize this document on Apr 26, and begin writing PRs next week. I have taken feedback and have incorporated these ideas into the proposal.
I have listed some areas for discussion above, https://s.apache.org/beam-fn-api-metrics Today, I will be updating one part of the document. I will be reserarching and proposing a new DistributionMetric format, to be compatible with metrics collection systems such as Stackdriver nad Dropwizard. The existing proto we had is not compatible with these systems, as it specified nothing about bucketing the distribution into a histogram.
