Hi, As I see it, if hinted handoff is enabled, the only time data can be inconsistent is when: 1. A node is down for longer than the max_hint_window 2. The coordinator node crushes before all the hints have been replayed Why is it still recommended to perform frequent automatic repairs, as well as enable read repair? Can't I just run a repair after one of the nodes is down? The only problem I see with this approach is a long repair job (instead of small incremental repairs). But other than that, are there any other issues/corner-cases? Cheers, Eugene
