We are excited to announce the next phase of the OpenTelemetry Protocol with Apache Arrow project (OTel-Arrow). We began this project several years ago with the goal of bridging between OpenTelemetry data and the Apache Arrow ecosystem. Apache Arrow is a framework designed for zero-copy exchange of structured data between column-oriented data producers and consumers.
We believe that having OpenTelemetry data accessible to external systems through Apache Arrow will lead to powerful integrations, with the potential for new telemetry systems and applications to emerge. For large streams of telemetry, we know that column-oriented data handling is substantially more efficient, with improved data compression and performance.
