Definition: A balanced k-way merge sort that sorts a data stream using repeated merges. It distributes the input into two streams by repeatedly reading a block of input that fits in memory, a run, sorting it, then writing it to the next stream. It then repeatedly merges the two streams and puts each merged run into one of two output streams until there is a single sorted output.
Generalization (I am a kind of ...)
