      • diff

        public static Map<String,​Object> diff​(ManagedIndexSchema oldSchema,
                                            ManagedIndexSchema newSchema)
        Compute difference between two managed schemas. The returned map consists of changed, new, removed elements in fields, field types, dynamic fields and copy fields between input schemas. 
         Output format when rendered to json will look like below:
   
   {
     "fields": {
       "updated": {...},
       "added": {...},
       "removed": {...}
     },
     "fieldTypes": {
       "updated": {...},
       "added": {...},
       "removed": {...}
     },
     "dynamicFields": {
       "updated": {...},
       "added": {...},
       "removed": {...}
     },
     "copyFields: {
       "new": [...],
       "old": [...]
     }
   }
        Parameters:
        oldSchema - instance of ManagedIndexSchema
        newSchema - instance of ManagedIndexSchema
        Returns:
        the difference between two schemas
