Hi Riak Users, I am a little bit confused about the metadata, it is stored in memory and synced in every node, so bascially every node share the same metadata, right ? But then from the official document, the formula to calcuate the RAM requirement, the RAM requirement is for whole cluster, for example, based on the formula below, the requirement is 50G, then if we have 5 nodes, then each node only needs 10G RAM. Seems the metadata is divided to different nodes, I must hvae misunderstood something, could someone please to clarify this, thank you very much.
