PhasedExecutionSchedule (trino-main 369 API)

java.lang.Object
- io.trino.execution.scheduler.policy.PhasedExecutionSchedule

All Implemented Interfaces:

ExecutionSchedule
```
public class PhasedExecutionSchedule
extends Object
implements ExecutionSchedule
```
Schedules stages choosing to order to provide the best resource utilization. This means that stages which output won't be consumed (e.g. join probe side) will not be scheduled until dependent stages finish (e.g. join build source stages). Contrary to LegacyPhasedExecutionPolicy, PhasedExecutionSchedule will schedule multiple source stages in order to fully utilize IO.
