/**
- * A {@link TimeWindow} covers a half-open time interval with its start
timestamp as an inclusive boundary and its end
- * timestamp as exclusive boundary.
- * It is a fixed size window, i.e., all instances (of a single {@link
org.apache.kafka.streams.kstream.TimeWindows
- * window specification}) will have the same size.
- * <p>
- * For time semantics, see {@link
org.apache.kafka.streams.processor.TimestampExtractor TimestampExtractor}.
+ * A {@link TimeWindow} is a time interval window container that holds the
start and end time for use in window-agnostic cases,
+ * ex: in {@link org.apache.kafka.streams.state.WindowStore}, we'll store the
aggregated values of any fixed-size types of time windows.
+ * We use {@link TimeWindow} to represent these time windows
