封闭类:

StatusWatermarkValve

@VisibleForTesting
protected static class StatusWatermarkValve.InputChannelStatus
extends Object

An InputChannelStatus keeps track of an input channel's last watermark, stream status, and whether or not the channel's current watermark is aligned with the overall watermark output from the valve.

There are 2 situations where a channel's watermark is not considered aligned:

• the current watermark status of the channel is idle
• the watermark status has resumed to be active, but the watermark of the channel hasn't caught up to the last output watermark from the valve yet.
