Display data is limited in that it doesn't provide a way to publish runtime metadata. > Aggregators are the current method for pipelines to publish runtime metadata, but currently focuses on counter-type metadata. It would be valuable to expand the support for dynamically-computed properties like "pub-sub subscription id" or "sink export job status". This would fit nicely into the aggregators API by providing a "Latest" combiner with String-typed data. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
