> As discussed
> [here|https://github.com/apache/flink/pull/6787#discussion_r247926320], we
> need a dedicated phase to materialize time indicators for nodes produce
> updates.
> Details:
> Currently, we materialize time indicators in `RelTimeInidicatorConverter`. We
> need to introduce another materialize phase that materializes all time
> attributes on nodes that produce updates. We can not do it inside
> `RelTimeInidicatorConverter`, because only later, after physical optimization
> phase, we know whether it is a non-window outer join which will produce
> updates
> There are a few other things we need to consider.
> - Whether we can unify the two converter phase.
> - Take window with early fire into consideration(not been implemented yet).
> In this case, we don't need to materialize time indicators even it produces
> updates.
