All available APIs for creating, updating and deleting objects in the Backendless database operate on single objects. It means when you need to store multiple objects in the database, each object requires a separate API call. This increases the number of API calls your app makes. While it is great for us (hey, our billing is based on the API calls), it is not that great for your app as it results in longer processing times and substandard user experience. Starting today, with the release of Backendless version 4.5.0 we’re introducing the new APIs which will allow you to create, update or delete multiple objects with a single API call.
Saving multiple new objects in the database is now as simple as passing an array of objects to the server. The server responds with a collection of objectId values (which, for example, can be used in the createRelation API). The bulk create API is supported in all SDKs as well as the REST interface.
To update objects in the database, the API accepts a condition (where clause) which identifies a group of objects. In addition to the condition, the client must also provide an object containing the changes which should be applies to the selected objects.
Similar to “Bulk Update”, this API receives a condition which identifies a group of objects to be deleted.
All of the APIs can be extended using custom business logic’s before/after events.
You can find the documentation for these APIs in the developer guides:
