Your Lambda function comes with a CloudWatch Logs log group and a log stream for each instance of your function. When you invoke a Lambda function, Lambda receives the invocation request and validates the permissions in your execution role, verifies that the event document is a valid JSON document, and checks parameter values. Lambda functions have access to metadata about their environment and the invocation request. This can be accessed at Package context . Should your handler include context.Context as a parameter, Lambda will insert information about your function into the context's Value property. Today, we’re excited to announce Go as a supported language for AWS Lambda.
