title: Easiest way to have a 100% copy of a Cosmos DB container
body: <p>I want two different containers in my Cosmos DB database to contain the exact same data all the time. The only difference will be the partition key of the container.</p>
  <p>What is the easiest way to accomplish this? I am looking for a method with none to little code so I do not like the Data Factory solution that the internet seems to recommend. Perhaps there is another service in Azure or a third party service - or maybe it can be done robustly with simple triggers?</p>
  <p>EDIT: Clarification - I need them to be continuously updated. One container is where all the data is changed during normal use and the other container should be kept synchronized as it happens.</p>
