title: Join table between Different Microservices
body: <p>I am still trying to make sense of micro service architecture.</p>
  
  <p>The idea to separate different application (include the database) excites me. But I am still confused if there are two micro-services e.g. Product and User. both product and user own table product and user respectively in their database. According to best practice in micro service, we only can access the database from the service. </p>
  
  <p>The problem is, let us suppose we have product table that has user_id column. We want to do search product which also return the name of the user who create the product. This requires join between product table in product micro-service and user table in user micro-service. How do you handle this? </p>
