In Cassandra 3.0 the default nodetool repair behaviour is incremental and parallel. Is there a downside to triggering repair from multiple nodes at the same time?
Basically, instead of scheduling a cron job on one node to run repair, I want to schedule the job on every node (this way, I don't have to worry about repair if the one node goes down). Alternatively, I could build a smarter solution for HA repair jobs, but that seems like an overkill.
