    Description

      The Lucene90 doc values producer optimizes for random access so that selective queries only have to decode the values that they need for sorting or faceting.

      However, in the case of merging, the merging process systematically consumes all doc IDs / values sequentially, so we could optimize for this access pattern via the merge instance?
