OTel Meets Wasm: Rethinking OpenTelemetry Collector Extensibility
summary
A proof‑of‑concept called autom proof-of-concept loads OpenTelemetry Collector receivers, processors and exporters as WebAssembly modules using wasmtime/wasm0 embedding, the wasmedge socket extension and a builder that swaps Go stdlib pieces so Go plugins need minimal source changes. Plugins load from HTTP or OCI images and a demo shows adding an attribute processor via OpAMP remote config takes 20 seconds to restore with no rebuild. The initial proto ABI is hundreds of times slower than native; a handle accessor API cuts that gap to ~13x but needs plugin rewrites and further optimization.
