Interface Span

All Known Implementing Classes:

SimpleSpan

@Experimental
public interface Span

Span represents something that happened in Flink at certain point of time, that will be reported to a TraceReporter.

Currently we don't support traces with multiple spans. Each span is self-contained and represents things like a checkpoint or recovery.
