Elasticsearch: Disable the Versioning of index document

Question

I could see the ElasticSearch versioning the index documents for every update. I would like to know if there is a way to disable these versions? I understand its a good to have functionality, but its just for exploring the tool. Also is there is any performance concerns with large number of versions?

Thanks

Versioning doesn't mean that elasticsearch keeps every version of the document. It keeps only the latest one. Every document has by default an implicit _version field, that gets incremented whenever the document changes. That allows for optimistic locking if you need it. You can also have your own external versioning system if you want. Have a look at this article that is all about versioning with elasticsearch.

This doesn't hurt performance at all, I wouldn't look into disabling it.
