Add a daily incremental repair job Cassandra 2.1 adds a new incremental repair mode, which should make daily repairs fairly fast. Lets see if the impact with -par is okay. If I understand the docs right it sounds like it would be a win over repairing each node sequentially, especially in combination with incremental repairs.
