Hi,
I'm using allocate_tokens_for_keyspace and num_tokens=32 and i wan't to extend the size of some clusters. I read in articles that for num_tokens=4, one should add more 25% of cluster size for the cluster to become balanced again. 1. For example, with num_tokens=4 and already have 16 nodes, so i should add 4 nodes to be balanced again and my cluster would be in dangerous and unbalanced state until i add the 4th node? Or should i add all 4 nodes at once (i don't know how because i should wait for each node to stream in multiple TBs)? 2. with num_tokens=32 for these different scenarios of cluster size, how many nodes should i add to be balanced again? a. cluster size = 16 b. cluster size = 32 c. cluster size = 70 3. I can not understand why cassandra could not keep cluster balanced when you add/remove a single node to the cluster, how the mechanism works? 4. Is the limitation the same with the shrink? Thank you in advance
