We want to use Elasticsearch as primary data source, and we also want to keep track of changes of document, so we want to store all the versions of a document.
As a solution will be to hide previous document versions from the index, is this possible?
Elasticsearch has _version field, which is increased if you make a update to the same document, while query you can specify to get the highest version of a document to get the latest document.
More information on how to do is in elasticsearch version support blog
Edit:- Question asked in comment is that can we get a particular version document and answer is yes, also mentioned in official doc https://www.elastic.co/guide/en/elasticsearch/reference/current/docs-get.html and you can get it using query param but it has to be the current version otherwise you will get version_conflict_engine_exception, sample request looks like
http://{{hostname}}:{{port}}/{{index-name}}/_doc/2?version={your doc version}
