From the cluster paged, It is said partitions need to be moved to other nodes when a node fails or new node added. In this case, does it means all data will be copied from one node to another?
If so, is there a best practice for the size limitation of a namespace? (If namespace is too big, saying 4T, then each partition of the namespace is about 1G, copying these partitions across cluster might be very resource consuming)
If the node is offline just for a few minutes (due to network issue let’s say), will migration continues? Or it will detect this and undo migration smartly?
