When using Couchbase in a VM, should the memory be the same for nodes that use the same service?
ex )
device 1(Memory 10GB) - data service
device 2(Memory 10GB) - data service
device 3(Memory 30GB) - data service
Memory Quotas : 5296MB
Is there a problem if memory is allocated as above?
We recommend keeping all the resources as consistent as possible for the nodes within a given service. This ensures that the software can treat them all the same, and if there is a failure of one, it doesn’t overwhelm the others.
Additionally, the memory quota will be limited by the node with the lowest available memory. So for device 3 above, you won’t actually be able to use the extra 20GB. Technically there shouldn’t be any issue with having the extra memory.
