Ismaël Mejía commented on BEAM-30:
----------------------------------
Does this one still apply? is this about `TriggerStateMachineRunner`?
> In TriggerRunner, avoid reading the set of finished subtriggers when no
> subtrigger ever finishes.

> URL: https://issues.apache.org/jira/browse/BEAM-30
> Project: Beam
> Issue Type: Improvement
> Components: runner-core
> Reporter: Kenneth Knowles
> Priority: Minor
> Labels: Triggers
>
> For a trigger expression, TriggerRunner tracks which of the subexpressions
> have finished to track which subexpression is the currently active trigger
> that determines when output is permitted. For some triggers (such as the
> default trigger) this information is not needed. The reads and writes of this
> data can be elided.
