title: Dynamo Db vs Elastic Search
body: <p>I was just reading about elastic search and found that it indexes each and every term in the document as well as all fields. Although it has some disadvantages like it cannot provide transactions, etc. But for the application, where I only need to read data from DB and there is no write, is there any advantage to using Dynamo Db instead of Elastic Search. Earlier, I was thinking to use the Dynamo Db, but now after seeing that it indexes each and every field, so why not use Elastic Search itself. Till now, the only use case defined for my project is to search by an id. But in future, more use cases come, then it would be very difficult to add more indexes in Dynamo Db but would already be there in Elastic Search. </p>
  
  <p>Can someone tell me of some advantages of Dynamo Db against Elastic Search.</p>
  
  <p>Please give your suggestions. </p>
