Hey everyone, We've just migrated to a new Cassandra cluster running 3.7 and wanted to get some information on best practices when running nodetool repair; our last cluster was 1.2 and per the documentation it seems that a lot of behavior has changed between those versions.
>From a read of the documentation, it looks like running nodetool repair without any additional arguments will perform a parallel, incremental on a specific node. For our first run of a repair, do we need to simply run this across all nodes in our cluster? When should we specify full vs incremental when doing repairs? Additionally, what are the implications of running repairs sequentially vs in parallel with regards to cluster load or completion time? Are there any best practices around running cluster wide manual repairs in 3.7? Any advice around how others have managed repairs would be greatly appreciated. Thanks! Dan
