------------------------------------------
Summary: Add HTTP support to OpenTelemetry Reporter
Key: FLINK-38154
URL: https://issues.apache.org/jira/browse/FLINK-38154
Project: Flink
Issue Type: Improvement
Components: Runtime / Metrics
Reporter: Kumar Mallikarjuna
*Motivation*
Currently, Flink's _{{OpenTelemetryMetricReporter}}_ only supports exporting
metrics via OTLP/gRPC. However, many modern observability platforms, like
Prometheus, ingest metrics using OTLP/HTTP. This limitation obstructs direct
integration with such systems.
While workarounds exist, such as deploying an intermediary OpenTelemetry
Collector to translate OTLP/gRPC to OTLP/HTTP, they add an extra dependency and
operational overhead.
*Goal*
Add OTLP support for HTTP in {_}{{OpenTelemetryMetricReporter}}{_}.
