StatusWatermarkValve |
A
StatusWatermarkValve embodies the logic of how Watermark and StreamStatus are propagated to downstream outputs, given a set of one or multiple input channels
that continuously receive them. |
StatusWatermarkValve.InputChannelStatus |
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. |
StreamStatus |
A Stream Status element informs stream tasks whether or not they should continue to expect
records and watermarks from the input stream that sent them.
