Hi, Mikhail, Ryan and I have been working on some metric related PRs recently. Robert has been reviewing and committing these changes, but we would like another reviewer to get another opinion and reduce the volume for Robert.
Ryan's goal is to implement the GetMetrics API <https://docs.google.com/document/d/1p7mRCUEigkrWickqCLCHBshrqQ97YIv1E5cZxJTKx3I/edit?ouid=113939718880580928184&usp=docs_home&ths=true> and enable querying for metrics in the Flink Runner. Mikhail and I are finishing adding some standard metrics for the python SDK and the Dataflow Runner, and writing integration tests (SDK metrics design <https://s.apache.org/beam-fn-api-metrics>): - Element Count - MeanByteCount - User Distribution Metrics Please let us know if you would be interested in learning more about metrics and get involved in reviewing the related PRs and we can add you as a reviewer.
