Hi, we are migrating to ES 6.x so we are redesigning our schemas. I am wondering which is better for performance ? to have multiple an index for each type or to create one index and add a new type field. I know that if we will put all the types in one index that would mean that elasticsearch will process all the docs. so this might mean lower performance. ---

The best answer we can give you is for you to test it yourself. There are a number of variables we don't know about that make it difficult to impossible to answer this sorry! ---
