Context properties

  • function_name – The name of the Lambda function.

  • invoked_function_arn – The Amazon Resource Name (ARN) that's used to invoke the function. Indicates if the invoker specified a version number or alias.

  • memory_limit_in_mb – The amount of memory that's allocated for the function.

  • aws_request_id – The identifier of the invocation request.

  • log_group_name – The log group for the function.

  • log_stream_name – The log stream for the function instance.

  • deadline_ms– The date that the execution times out, in Unix time milliseconds.
