class ConfigOrchestrator(ConfigBase):
"""
Main config of the orchestrator components.
:cvar ConfigField[bool] cycle_control:
This boolean flag enables the orchestrator to detect cycles of calls to subtasks.
For example, if task1 calls task2 and task2 calls back to task1, this can create
an endless loop. The cycle control functionality is enabled by default to prevent
such scenarios. Users can choose to disable it if needed.
:cvar ConfigField[bool] blocking_control:
This boolean flag activates control over tasks that are blocking on other tasks.
If a task invocation is waiting on another invocation, it notifies the runner,
which temporarily removes it from the processing queue and uses the slot for
another task invocation. Once the required invocation finishes, the dependent
invocation is placed back into the run queue. This feature also prioritizes
invocations that have many dependencies over new ones, ensuring efficient
task management.
:cvar ConfigField[float] auto_final_invocation_purge_hours:
This float value, defaulting to 24.0 hours, sets the duration after which the
orchestrator purges all invocations older than the specified time. This purge
mechanism helps keep the orchestrator lightweight and fast, as it should
ideally operate with minimal latency. Detailed information about the invocations
is stored in the result backend, which can handle more data and afford to be slower.
