ability to capture all metric raw data without aggregation #617
Description
In OT Metric API Instruments Spec, we defined that each type of metric instrument should be binding with a default aggregation behavior / aggregator. In AWS CloudWatch, we support to capture all raw metric measurement events and assemble it as Embedded Metric Format(EMF) in a structured log and so CloudWatch backend can process all raw metric data and provide all metrics visualization capabilities.
We'd like to implement such Exporters for SDK and Collector to support EMF metric format but it requires that we can capture all the raw metric events without aggregating. I see we have Views API WIP to allow customers customizing aggregator. We do want to start the work on this ASAP and looking for the suggestions here if there is a way we can capture all the raw metrics event data(especially not SummaryDataPoint) and pass it to OT collector so we can bring in AWS exporters to support it? Thanks.
