[jira] [Created] (LUCENE-8608) Extract utility class to iterate over terms docs

Simon Willnauer created LUCENE-8608:
---------------------------------------

             Summary: Extract utility class to iterate over terms docs
                 Key: LUCENE-8608
                 URL: https://issues.apache.org/jira/browse/LUCENE-8608
             Project: Lucene - Core
          Issue Type: Improvement
            Reporter: Simon Willnauer
             Fix For: master (8.0), 7.7


Today we re-implement the same algorithm in various places
when we want to consume all docs for a set/list of terms. This
caused serious slowdowns for instance in the case of applying
updates fixed in LUCENE-8602. This change extracts the common
usage and shares the interation code including logic to reuse
Terms and PostingsEnum instances as much as possble and adds
tests for it.
