object MinWatermark extends MultipleWatermarkPolicy with Product with Serializable

Policy to choose the *min* of the operator watermark values as the global watermark value. Note that this is the safe (hence default) policy as the global watermark will advance only if all the individual operator watermarks have advanced. In other words, in a streaming query with multiple input streams and watermarks defined on all of them, the global watermark will advance as slowly as the slowest input. So if there is watermark based state cleanup or late-data dropping, then this policy is the most conservative one.
