Membase mode and backing store questions
I have a couple of questions on membase mode.
1) If I allocate 5GB of memory on each server server in the cluster, does each server need to have at least 5GB of disk space free? Can it be less?
2) It is my understanding that membase mode doesn't use slabs, while memcache mode does. Can I assume that membase mode is more effecient and better at allocating memory to minimize evictions?
3) As I add more servers to the cluster will the size of each bucket increase by the default size. For example, if I have a bucket that allocated 5GB per server. I already have two servers in the cluster, so the total RAM available to the bucket is 10GB. If I add a new server, will the total RAM for the bucket increase to 15GB?
