Repairs in Cassandra and Cassandra Reaper

Reaper is an open source tool that aims to schedule and orchestrate repairs of Apache Cassandra clusters. It improves the existing nodetool repair process by Splitting repair jobs into smaller tunable segments. Handling back-pressure through monitoring running repairs and pending compactions.
