Usage

Register Generic Pool Adapter on app.json as follows:

"adapterTypes": [
    ...
    { "name":"...", "invariantName": "...", "type":"..." },
    { "name":"Pool Data Adapter", "invariantName": "pool", "type":"@themost/pool" }
    ...
],
adapters: [
    ...
    { "name":"development", "invariantName":"...", "default":false,
        "options": {
          "server":"localhost",
          "user":"user",
          "password":"password",
          "database":"test"
        }
    },
    { "name":"development_with_pool", "invariantName":"pool", "default":true,
                "options": {
                  "adapter":"development"
                }
            }
