const cacheConfig = process.env.CACHE_CONFIG || 
  { type : 'redis', 
    connection : {
      host : '127.0.0.1',
      port : 6379
    }
  };

const cache = Cache.create( { cacheConfig, namespace : 'myApp'} )
...
await cache.set( 'myKey', myValue )  // This will set a value to a global myKey
const v = await cache.get( 'myKey' ) // This will access a global myKey
await cache.setNs( 'myKey', myValue )  // This will set a value to a namespaced myKey (myApp:myKey)
const v = await cache.getNs( 'myKey' ) // This will access a namespaced myKey (myApp:myKey)

Other usage
