Metrics Exporter - In-memory

Status: Stable

In-memory Metrics Exporter is a Push Metric Exporter which accumulates metrics data in the local memory and allows to inspect it (useful for e.g. unit tests).

In-memory Metrics Exporter MUST support both Cumulative and Delta Temporality.

If a language provides a mechanism to automatically configure a MetricReader to pair with the associated exporter (e.g., using the OTEL_METRICS_EXPORTER environment variable), by default the exporter MUST be paired with a periodic exporting MetricReader.
