Extracting from parent issue to own issue to gather explicit feedbacks, as details are hard to notice, when embedded inside the parent issue, especially the breaking changes.
Following sub-sections provides details on items we plan for each release, along with rough timelines.
Beta release - ETA June 30 2024
Breaking changes are still possible in beta, but has a higher bar than alpha releases.
The following functionality is explicitly being removed:
Metrics API's ability to add/remove Callbacks after Observable Instruments has been created. There will still be ability to provide callback(s) at the time of Instrument Creation. The current API to add/remove callbacks after instrument creation needs to be revisited to ensure functionality/usefulness/correctness. Removing it from initial release to keep the scope manageable.
Metrics SDK's View feature. Would need to gather feedback about the common use cases where Views are needed. My own experience is that, it is used most frequently to provide custom Histogram bounds. Before removing View feature, the ability to provide custom bounds will be provided at the API level. The main reason why it is removed from initial release is to keep scope manageable. Views bring a whole lot of new complexities and additional test requirements.
Prometheus/Pull Exporter.
RC release - ETA Nov 30 2024
