[jira] [Updated] (LUCENE-7545) Dense norms/doc values should not consume memory in the IW buffer to store the set of docs with a value for the field

Adrien Grand updated LUCENE-7545:
---------------------------------
    Attachment: LUCENE-7545.patch

Here is a patch. It adds a DocsWithFieldSet helper class that first assumes all docs have a value for the field and only stores the highest docID seen so far, and migrate to a FixedBitSet if there is a gap.

> Using a bit set to store docs that have a value for a field is great for sparse doc values, but it is a pity we have to pay this price for dense doc values too.
