> How to handle operators that don't provide metrics such as potentially user defined ones (probably will fill in with their parents) I think there is also the case where user defined operators are the parents and we need to generate metrics recursively for their children too for end to end tracing. The list of metrics look like stuff that can be automatically generated across all operators if we can force all operator implementations to follow a certain convention. For example, instead of calling `execute` method directly, have all operator call a wrapper execute method that handles the builtin metrics collection. That way, it just becomes something all operators will out of the box in a consistent way. -- This is an automated message from the Apache Git Service.
