I'm glad your index throttling is fixed.

Doc values inherently consume disk space ... this is the tradeoff vs field data (which consumes java heap).

But, do you have very sparse fields? Or, many different types where each type has different fields? The storage format for doc values is not sparse, so this can consume more disk space than you expect ...
