---------------------------------------
Summary: Share internal DV update code between binary and numeric
Key: LUCENE-8272
URL: https://issues.apache.org/jira/browse/LUCENE-8272
Project: Lucene - Core
Issue Type: Improvement
Affects Versions: 7.4, master (8.0)
Reporter: Simon Willnauer
Fix For: 7.4, master (8.0)
Attachments: LUCENE-8272.patch
Today we duplicate a fair portion of the internal logic to
apply updates of binary and numeric doc values. This change refactors
this non-trivial code to share the same code path and only differ in
if we provide a binary or numeric instance. This also allows us to
iterator over the updates only once rather than twice once for numeric
and once for binary fields.
This change also subclass DocValuesIterator from
DocValuesFieldUpdates.Iterator
which allows easier consumption down the road since it now shares most of
it's
interface with DocIdSetIterator which is the main interface for this in
Lucene.
