I am the [Flink Jira Bot|https://github.com/apache/flink-jira-bot/] and I help 
the community manage its development. I see this issues has been marked as

ticket is a Major, please either assign yourself or give an update. Afterwards, 
please remove the label or in 7 days the issue will be deprioritized.

> 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.
