public class PerFieldMapperCodec extends org.apache.lucene.codecs.lucene92.Lucene92Codec
This Lucene codec provides the default PostingsFormat and KnnVectorsFormat for Elasticsearch. It utilizes the MapperService to lookup a PostingsFormat and KnnVectorsFormat per field. This allows users to change the low level postings format and vectors format for individual fields per index in real time via the mapping API. If no specific postings format or vector format is configured for a specific field the default postings or vector format is used.
