Description

Motivation

FLIP-384 is adding TraceReporter interface. However with FLIP-384 alone, Log4jTraceReporter would be the only available implementation of TraceReporter interface, which is not very helpful.

In this FLIP I’m proposing to contribute both MetricExporter and TraceReporter implementation using OpenTelemetry.
