Roaring+Run refers to a modified version of the Roaring bitset compression scheme which has an additional container type to represent runs of a single (set) bit. The run container stores the lower 16-bits of bit position of the start of the run, and then it uses another 16-bit value to store the length of the run. For more, this paper from David Lemire is a good start: https://arxiv.org/pdf/1402.6407.pdf Thanks, Taylor
