Re: Consistent vs inconsistent range movements

Imagine you have a cluster with RF=3, and you write a key with CL:QUORUM, it goes to nodes 1 and 3, but node 2 is offline. Some time later, node 2 comes online. Then you want to add node 2.5 in between nodes 1 and 3. If you stream data from node 2, you violate consistency guarantees (quorum) -

Consistent vs inconsistent range movements

Hi, Can anyone tell the difference between consistent + inconsistent range movements? What exactly makes them consistent or inconsistent? In what situations can both of them occur? It would be great to get a correct and deep understanding of that for further MV improvments. My intuition tells me
