Bulk operations

Appwrite Databases supports bulk operations for documents, allowing you to create, update, or delete multiple documents in a single request. This can significantly improve performance for apps as it allows you to reduce the number of API calls needed while working with large data sets.

Bulk operations can only be performed via the server-side SDKs. The client-side SDKs do not support bulk operations by design to prevent abuse and protect against unexpected costs. This ensures that only trusted server environments can perform large-scale data operations.

For client applications that need bulk-like functionality, consider using Appwrite Functions with proper rate limiting and validation.

Atomic behavior

Bulk operations in Appwrite are atomic, meaning they follow an all-or-nothing approach. Either all documents in your bulk request succeed, or all documents fail.

This atomicity ensures:

• Data consistency: Your database remains in a consistent state even if some operations would fail.

• Race condition prevention: Multiple clients can safely perform bulk operations simultaneously.

• Simplified error handling: You only need to handle complete success or complete failure scenarios.

For example, if you attempt to create 100 documents and one fails due to a validation error, none of the 100 documents will be created.
