When creating a new collection in the persistent data storage layer, Kuzzle uses a default mapping. This means that, by default, you won't be able to exploit the full capabilities of our persistent data storage layer (currently handled by ElasticSearch (opens new window)), and your searches may suffer from below-average performance, depending on the amount of data you stored in a collection and the complexity of your database.
The CollectionMapping object allows you to get the current mapping in a collection and to modify it if necessary.
CollectionMapping(Collection, [mapping]) #
| ||Collection||An instantiated Collection object|
| ||JSON Object||Optional mapping|
| ||JSON Object||Common headers for all sent documents.||get/set|
| ||object||Easy-to-understand list of mappings per field||get/set|
headers property is inherited from the provided Collection object and can be overrided
/* Constructors are not exposed in the JS/Node SDK. CollectionMapping objects are returned by the method Collection.getMapping You may also use the Collection.collectionMapping() method: */ var mapping = kuzzle.collection('collection', 'index').collectionMapping(); mapping = kuzzle.collection('collection', 'index').collectionMapping(mapping);
