## URL path parts

Many Elasticsearch url paths allow dynamic values. These SHOULD be recorded in span attributes in the format
`db.elasticsearch.path_parts.<key>`, where `<key>` is the url path part name. The implementation SHOULD
reference the [elasticsearch schema](https://raw.githubusercontent.com/elastic/elasticsearch-specification/main/output/schema/schema.json)
