juan camilo rodriguez duran updated LUCENE-9236:
------------------------------------------------
Description:
Today DocValues Consumer/Producer require override 5 different methods, even
if you only want to use one and given that one given field can only support one
doc values type at same time.
In the attached PR I’ve implemented a new modular version of those classes
(consumer/producer) each one having a single responsibility and writing in the
same unique file.
This is mainly a refactor of the existing format opening the possibility to
override or implement the sub-format you need.
I’ll do in 3 steps:
# Create a CompositeDocValuesFormat and moving the code of
Lucene80DocValuesFormat in separate classes, without modifying the inner code.
At same time I created a Lucene85CompositeDocValuesFormat based on these
changes.
# I’ll introduce some basic components for writing doc values in general such
as:
## DocumentIdSetIterator Serializer: used in each type of field based on an
IndexedDISI.
## Document Ordinals Serializer: Used in Sorted and SortedSet for deduplicate
values using a dictionary.
## Document Boundaries Serializer (optional used only for multivalued fields:
SortedNumeric and SortedSet)
## TermsEnum Serializer: useful to write and read the terms dictionary for
sorted and sorted set doc values.
# I’ll create the new Sub-DocValues format using the previous components.
