Hello, We run Cassandra 2.1.13 (don't have plans to upgrade yet). What is the best way to run repairs at scale (400 nodes, each holding ~600GB) that actually works ?
I'm considering doing subrange repairs (https://github.com/BrianGallew/cassandra_range_repair/blob/master/src/range_repair.py) as I've heard from folks that incremental repairs simply don't work even in 3.x (Yeah, that's a strong statement but I heard that from multiple folks at the Summit). Any guidance would be greatly appreciated ! Thanks, Anubhav
