This is a breakout issue for #2603. My intent is to consolidate the discussion so that we can get help from someone at Datadog to resolve this issue.
In #2603 a Vector user asked us to support the DogStatsd Distribution type metric. While implementing this change we discovered that we cannot simply send distribution metrics to Datadog because it appears to be an undocumented API feature. We discovered that the Datadog agent aggregates distribution metrics into Datadog's custom sketch type and then forwards them via an undocumented v2 API based on protocol buffers.
In order for us to support Datadog distribution metrics, we need someone from Datadog to tell us how we can use their API to send distribution type metrics.
