Can I do both replication and sharding? about mcrouter

[didip]

I got it. This config does what I want:

{
  "pools": {
    "Replica1": { "servers": ["localhost:11211", "localhost:11212"] },
    "Replica2": { "servers": ["localhost:11213", "localhost:11214"] },
    "Replica3": { "servers": ["localhost:11215", "localhost:11216"] }
  },
  "route": {
    "type": "OperationSelectorRoute",
    "default_policy": "PoolRoute|Replica1",
    "operation_policies": {
      "add": {
        "type": "AllSyncRoute",
        "children": [ "PoolRoute|Replica1", "PoolRoute|Replica2", "PoolRoute|Replica3" ]
      },
      "set": {
        "type": "AllSyncRoute",
        "children": [ "PoolRoute|Replica1", "PoolRoute|Replica2", "PoolRoute|Replica3" ]
      },
      "delete": {
        "type": "AllSyncRoute",
        "children": [ "PoolRoute|Replica1", "PoolRoute|Replica2", "PoolRoute|Replica3" ]
      },
      "get": {
        "type": "LatestRoute",
        "children": [ "PoolRoute|Replica1", "PoolRoute|Replica2", "PoolRoute|Replica3" ]
      }
    }
  }
}

Sorry that I am wasting y'all time, I should have just read the source directly.
