--------------------------------------
Summary: Introduce mailbox to StreamTask main-loop
Key: FLINK-12480
URL: https://issues.apache.org/jira/browse/FLINK-12480
Project: Flink
Issue Type: Sub-task
Components: Runtime / Operators
Reporter: Stefan Richter
In this sub-task, we introduce the mailbox data-structure to the
{{StreamTask}}'s main-loop that runs the step-wise actions. After this
sub-task, the mailbox events should already be respected, but the loop will
currently still always find that the mailbox is empty because it is not yet
integrated with the events that we will include in the next sub-tasks.
