-----------------------------------
Summary: fix SortedDocValues to no longer extend BinaryDocValues
Key: LUCENE-9796
URL: https://issues.apache.org/jira/browse/LUCENE-9796
Project: Lucene - Core
Issue Type: Improvement
Reporter: Robert Muir
SortedDocValues give ordinals and a way to derefence ordinal as a byte[]
But currently they *extend* BinaryDocValues, which allows directly calling
{{binaryValue()}}.
This allows them to act as a "slow" BinaryDocValues, but it is a performance
trap, especially now that terms bytes may be block-compressed (LUCENE-9663).
I think this should be detangled to prevent performance traps like LUCENE-9795:
SortedDocValues shouldn't have the trappy inherited {{binaryValue()}} method
that implicitly derefs the ord for the doc, then the term bytes for the ord.
