This is a lightweight alternative to the SolarWinds distribution of the OpenTelemetry collector for AWS Lambda. It can be used as a drop-in replacement for most use-cases, while weighting only a few megabytes. As such, it can speed up cold start times as there is less data to download to the environment, and uses less memory.
The collector listens for HTTP/OTLP, HTTP/JSON and gRPC/OTLP traces, metrics, logs and profiles on ports 4317 and 4318. It also collects logs output from the Lambda function, and will attempt to correlate them with the request trace whenever possible. It supports both classic and managed Lambda instances.
This collector uses the same SW_APM_API_TOKEN and SW_APM_DATA_CENTER environment variables as the full collector. It does not support configuration via a yaml file, or any custom processing logic.
These are updated on new commits to main, or manually by triggering CI workflow.

The collector requires a nightly Rust toolchain in order to build the standard library while optimizing for a small binary size. It uses the standard Cargo workflow, just run cargo build. rustfmt and clippy are run in CI, which will fail if there are any warnings.
The primary goal of this collector is to be lightweight, as such dependencies should be vetted and kept to a minimum, and niche features should be kept to the Go collector if they might bloat this collector for people who do not need them.
