Quickly access shadow of multiple things

Question

Hello,  
We want to show the current status of our things in a web interface. Their state is stored in each individual shadow. What is the easiest way to access 100+ shadows quickly?  
We are using Java and the only way to access the message broker I found in the java SDKs is in the device SDK. However, AWSIotMqttClient connection is limited to 50 subscription which makes it hard to manage many shadows at once.  
What is the intended way to access the shadow from a web application  backend?  
  
Thanks in advance!

Hi Gepro,  
  
This sounds like a potential use case for fleet indexing and maybe dynamic thing groups. With this feature enabled, you could write a query that returns a bunch of shadows in one go. Check out these features:
