Struct rlink::core::watermark::Watermark

pub struct Watermark { /* fields omitted */ }

Watermarks are the progress indicators in the data streams. A watermark signifies that no events with a timestamp smaller or equal to the watermark’s time will occur after the water. A watermark with timestamp T indicates that the stream’s event time has progressed to time T.

Watermarks are created at the WatermarkAssigner and propagate through the streams and operators.

Note: A stream’s time starts with a watermark of 0u64.
