Now that Lucene 8.8 supports configurable docvalues compression, I would ideally be able to remove the index.elastiknn setting and just let users decide whether they want to optimize for search speed or size on disk.

However, elasticsearch currently doesn't support a best_speed option for index.codec. I requested this to be added: elastic/elasticsearch#71788

For now, if anyone finds the index.elastiknn setting problematic or annoying, you can work around it and keep the same performance by setting index.codec to "lucene_default".

Seems the plan is to remove doc values compression all-together for newer versions of Lucene: https://issues.apache.org/jira/browse/LUCENE-9843

This was merged and looks like it will be out in 9.0. ES is currently on Lucene 8.8.x
