description: > Provides lightweight instrumentation of the Lambda core library, supporting all versions. It generates FaaS server spans with the `faas.invocation_id` attribute. Use this package if you only use `RequestStreamHandler` or know you don't use any event classes from `aws-lambda-java-events`. This also includes when you are using `aws-serverless-java-container` to run e.g., a Spring Boot application on Lambda. For custom wrappers when using library instrumentation, you can configure the `OTEL_INSTRUMENTATION_AWS_LAMBDA_HANDLER` environment variable to contain your lambda handler method (in the format `package.ClassName::methodName`) and use one of wrappers as your lambda `Handler`. library_link: https://docs.aws.amazon.com/lambda/latest/dg/java-handler.html configurations: - name: otel.instrumentation.aws-lambda.flush-timeout type: int default: 10000 description: Flush timeout in milliseconds.
