Hey,

see https://github.com/elastic/elasticsearch/pull/8536 - it was never supposed for production and was not propertly tested, so it got removed.

Also, not putting documents in your heap but in the filesystem cache (just use less heap in ES and so the operating system can load all the files into memory and then ES acts similar) should work for you as well.
