Class ExecuteProduceConsume
- All Implemented Interfaces:
Runnable
,ExecutionStrategy
A strategy where the thread that produces will always run the resulting task.
The strategy may then dispatch another thread to continue production.
The strategy is also known by the nickname 'eat what you kill', which comes from the hunting ethic that says a person should not kill anything he or she does not plan on eating. In this case, the phrase is used to mean that a thread should not produce a task that it does not intend to run. By making producers run the task that they have just produced avoids execution delays and avoids parallel slow down by running the task in the same core, with good chances of having a hot CPU cache. It also avoids the creation of a queue of produced tasks that the system does not yet have capacity to consume, which can save memory and exert back pressure on producers.
