ElasticsearchIndexInitializer

Creates the concrete Elasticsearch indices whose definitions an application ships: for each aggregate, META-INF/wow/elasticsearch/{indexName}.json on the classpath or config/wow/elasticsearch/{indexName}.json in the working directory, a native create-index request (settings, mappings, aliases). An index that does not exist yet is created from it; the index templates matching its name still apply beneath it, the definition winning where both map a field. The definition is found under the index's unprefixed name and creates the index indexNaming names.

An existing index keeps its mapping: Wow never changes it. When the mapping differs from its definition at a path the definition maps (an index created from the templates alone, before the definition shipped), startup logs a warning naming those paths, since queries on them are refused or answer from a mapping the application did not intend.
