org.elasticsearch.index.codec.postingsformat.PostingsFormatProvider

A {@link PostingsFormatProvider} acts as a named container for specific{@link PostingsFormat} implementations. Custom {@link PostingsFormat}implementations can be exposed via {@link CodecModule#addPostingFormat(String,Class)}

Each {@link PostingsFormatProvider} must provide a unique name for itspostings format in order to map the postings format to a specific field via the mapping API. The name provided via {@link #name()} is used to lookup thepostings format in {@link PostingsFormatService#get(String)} and should beidentical to the values used in the field mappings.

{@link PostingsFormatProvider} instances are initialized with a{@link Settings} subset below the{@value PostingsFormatProvider#POSTINGS_FORMAT_SETTINGS_PREFIX} prefix andwill only see the sub-tree below their mapping name. For instance a postings format ElasticFantastic will see settings below index.codec.postings_format.elastic_fantastic given that the postings format is exposed via index.codec.postings_format.elastic_fantastic.type : "ElasticFantastic".
