I am very late on two things. I missed last week post and the technology I am going to discuss here has been popular in the last few years. Today post is about PrestoDB or Presto for short. For those of you who are like me few months ago, Presto is NOT a database. I know it ends with DB in it but it is not a database. It is a query engine to query database(s).
Query engine is just a tool that acts like middleware between client and the real data storage or database. But if it is just an extra layer would it be just slowing down the query time? We’ll find out.
