Reaper splits repair runs in segments. A segment is a subrange of tokens that fits entirely in one of the cluster token ranges. The minimum number of segments for a repair run is the number of token ranges in the cluster. With a 3 nodes cluster using 256 vnodes per node, a repair run will have at least 768 segments. If necessary, each repair can define a higher number of segments than the number of token ranges.

**Starting with Reaper 1.2.0 and Cassandra 2.2, token ranges that have the same replicas can be coalesced into a single segment.** If the total number of requested segments is lower than the number of vnodes, Reaper will try to group token ranges so that each segment has the appropriate number of tokens.
