Hi All, We are thinking of migrating from primary range repair (-pr) to incremental repair.
Environment : * Cassandra 2.1.16 * 25 Node cluster , * RF 3 * Data size up to 450 GB per nodes We found that running full repair will be taking around 8 hrs per node which means 200 odd hrs. for migrating the entire cluster to incremental repair. Even though there is zero downtime, it is quite unreasonable to ask for 200 hr maintenance window for migrating repairs. Just want to know how Cassandra users in community optimize the procedure to reduce migration time ? Thanks & Regards Amit Singh
