Hi, It is possible to pass a boolean query parameter `local` [1] that controls whether or not the master node should be accessed when resolving a field's mapping. Can you clarify how the information differs when that is retrieved locally versus on the master node ? Thanks, [1] [https://www.elastic.co/guide/en/elasticsearch/reference/current/indices-get-field-mapping.html#get-field-mapping-api-query-params](https://www.elastic.co/guide/en/elasticsearch/reference/current/indices-get-field-mapping.html#get-field-mapping-api-query-params) ---

This parameter should be deprecated as it is not used anymore. Request is always executed locally. Thanks. ---
