This document serves to highlight key breaking changes for our customers. It does not represent the full list of breaking changes. As always, we recommend you test your searches on the new version of Elasticsearch before moving forward.
Elasticsearch 7 has a stand out breaking change which is the removal of mapping types. Before this version all versions of Elasticsearch supported the concept of mapping types, which would let you store different "types" of data in one index. Elastic is removing this feature after announcing its deprecation in ES 6.
This has been the standard recommendation for the best performance in Elasticsearch since its inception. Rather than index multiple types of documents into a single index, simply use one index per document type. Many tools and frameworks supporting Elasticsearch will do this for you automatically.
For those times when it simply doesn't make since to have one document type per index, you can add a dedicated field to the document that declares a document's given type. Then when you query on that index you will simply pass in which type you want the query limited to as well.
