Both quotas are "just watermarks". Node quota is just bound for sum of bucket quotas. And bucket quota is a bound which couchbase will try "really hard" not to exceed. But memory allocator fragmentation is not taken into account when couchbase decided if it has memory or if it doesn't. That's why giving it 63 gigs of ram out of 64 is some small kind of suicide in operation terms. -- You received this message because you are subscribed to the Google Groups "Couchbase" group.
