OTel-Arrow Phase 2: From Efficient Transport to Efficient Telemetry Pipelines

Phase 1 of OTel-Arrow established OTAP, the OpenTelemetry Arrow Protocol, as an efficient transport protocol for OpenTelemetry. Apache Arrow is a language-independent, columnar in-memory format designed to move and process structured data efficiently across systems. We demonstrated that telemetry could be transported with significantly lower network overhead while preserving compatibility with the OpenTelemetry data model.
