public final class SubtaskConnectionDescriptor
extends RuntimeEvent

An event that is used to (de)multiplex old channels over the same new channel.

During unaligned checkpoint recovery, if there is a rescaling, channels from the previous run may not be available anymore for restoring the data. In that case, the data of several old channels is sent over the same new channel through multiplexing. Each buffer is following this SubtaskConnectionDescriptor such that the receiver can demultiplex them.
