According to the documentation, it seems that the memcached buckets does not support rebalancing any more. Can someone please confirm?(https://developer.couchbase.com/documentation/server/5.5/understanding-couchbase/buckets-memory-and-storage/buckets.html)
Does this mean that in a cluster of 2 nodes of memcached buckets, data is not distributed evenly between the nodes?
Memcache buckets never supported “rebalance” in the Couchbase bucket / vBucket sense.
While you can add and remove nodes and a memcache bucket will redistribute the keyspace across the new node count (using the Ketama hashing algorithm), existing data is not actually moved as it is with a rebalance.
Thank you for the clarification.
Does the distribution of key spaces happen automatically whenever a node goes down? or Manual intervention is needed?
