title: How to get all aggregates with Axon framework?
body: <p>I am starting out with the Axon framework and hit a bit of a roadblock.</p>
  
  <p>While I can load individual aggregates using their ID, I can’t figure out how to get a list of all aggregates, or a list of all aggregate IDs.</p>
  
  <p>The <code>EventSourcingRepository</code> class only has <code>load()</code> methods that return one aggregate.</p>
  
  <p>Is there a way to all aggregate (IDs) or am I supposed to keep a list of all aggregate IDs outside of axon?</p>
  
  <p>To keep things simple I am only using an <code>InMemoryEventStorageEngine</code> for now.
  I am using Axon 3.0.7.</p>
