Struct StreamingJoinWindow 

Source 
pub struct StreamingJoinWindow { /* private fields */ }
Expand description

Event-time interval join settings.

Implementations§

Source§

impl StreamingJoinWindow

Source

pub fn new( time_column: impl Into<Arc<str>>, max_time_difference: Duration, ) -> Self

Creates a windowed join policy.

time_column must exist on both join inputs after scan projection.

Source

pub fn time_column(&self) -> &str

Returns the input timestamp column used for retention and late-row checks.

Source

pub const fn max_time_difference(&self) -> Duration

Returns the maximum allowed timestamp distance between joined rows.
