Which source replica does rebuild stream from?

Hi, We're looking into adding a second datacenter to our cluster via a rebuild, and we're curious on how Cassandra determines which source replica to rebuild from in the source datacenter. For a bit more context, we're using the Ec2Snitch with dynamic snitch enabled, and are using NetworkTopologyS

Re: Which source replica does rebuild stream from?

Hi both, thank you for your responses! Yes Jeff, we expect strictly correct responses. Our starting / ending topologies are near-identical (DC1: A/B/C, DC2: A/B/C), and reads are performed at LOCAL_QUORUM, while writes are done at EACH_QUORUM or ALL. Thanks, Sam On Thu, Nov 25, 2021 at 9:38 AM J
