There are current features (eg. update API) and future features (eg. reindex API) that depend on _source. This change locks down the field so that\r\nit can no longer be disabled. It also removes legacy settings compress/compress_threshold.\r\n\r\nFor users who \"dont use\" _source, we have a best_compression option that will store it with generally half the space of previous versions, still keeping the ability to reindex. For users concerned with indexing speed, a lot of work was put into stored fields merging/compression in Lucene 5.\r\n\r\ncloses #8142"},"comment":{"url":"https://api.github.com/repos/elastic/elasticsearch/issues/comments/98210081","html_url":"https://github.com/elastic/elasticsearch/pull/10915#issuecomment-98210081","issue_url":"https://api.github.com/repos/elastic/elasticsearch/issues/10915","id":98210081,"user":{"login":"jpountz","id":299848,"avatar_url":"https://avatars.githubusercontent.com/u/299848?v=3","gravatar_id":"","url":"https://api.github.com/users/jpountz","html_url":"https://github.com/jpountz","followers_url":"https://api.github.com/users/jpountz/followers","following_url":"https://api.github.com/users/jpountz/following{/other_user}","gists_url":"https://api.github.com/users/jpountz/gists{/gist_id}","starred_url":"https://api.github.com/users/jpountz/starred{/owner}{/repo}","subscriptions_url":"https://api.github.com/users/jpountz/subscriptions","organizations_url":"https://api.github.com/users/jpountz/orgs","repos_url":"https://api.github.com/users/jpountz/repos","events_url":"https://api.github.com/users/jpountz/events{/privacy}","received_events_url":"https://api.github.com/users/jpountz/received_events","type":"User","site_admin":false},"created_at":"2015-05-01T19:16:49Z","updated_at":"2015-05-01T19:16:49Z","body":"Thanks @rjernst it looks good!"}}
