"WebMerge runs R1 and R2. This is carried out by first reading one block of each of these runs into input buffers. Blocks of runs are merged from the input buffers into the output buffer. When the output buffer gets full, it is written out onto disk. If an input buffer gets empty, it is refilled with another block from the same run. " - K-way merge operation
