Time interval context for external schedulers.

TimeIntervalContext Objects

@configspec
class TimeIntervalContext(ContainerInjectableContext)

View source on GitHub

Active time interval from an external scheduler or dlt runtime.

Created with a concrete (start, end) datetime tuple, or autodetects from dlt env vars / Airflow. Partial intervals (start without end) are treated as no interval.

allow_external_schedulers

Override per-incremental allow_external_schedulers.

interval

@property
def interval() -> Optional[TTimeInterval]

View source on GitHub

Resolved interval as (start, end) datetime tuple, or None.

Returns the interval explicitly passed to the constructor when set; otherwise re-runs auto-detection on each access so callers always see the current runtime interval rather than a value cached at init time.

get_interval_context

def get_interval_context() -> Optional[TimeIntervalContext]

View source on GitHub

Get the active interval context from Container, or None.
