title: How to read multiple Sets stored on Redis using some command or LUA script
body: <p>I want to get all the sets from Redis using a list of keys in single call. As per the documentation, Redis provides SSCAN command for that but as I am using StackExchange.Redis as a Redis adapter, I guess this command does not have any such method in this adapter. So there two things I am looking for:</p>
  
  <ul>
  <li>I looking forward to execute SSCAN using the LUA script but was not able to find any such example over the internet. Can anyone share how to call SSCAN from LUA with multiple SET Keys.</li>
  <li>Also for the StackExchange.Redis, if I execute multiple SetMembers() in a transaction, is it similar to use SSCAN() command using LUA script?</li>
  </ul>
  
  <p>Thanks</p>
