How do you handle Batch or Bulk POST requests in REST APIs?
❓ Interview Prompt: Explain Bulk API design patterns, batch array payloads, atomic transactions vs partial successes (`207 Multi-Status`), and payload size limits.
Executing multiple resource mutations in a single round-trip using Batch/Bulk API endpoints:
Design Options:
1
Atomic Bulk Endpoint ('POST /api/v1/users/batch'): Accepts JSON array of item objects. Executes inside a single database transaction. Returns '201 Created' or rolls back entirely on error.
2
Partial Success ('207 Multi-Status'): Executes each item independently and returns an array of individual status codes per item index.
Code Implementation Example
json
// POST /api/v1/users/batch
{
"items": [
{ "name": "Alice", "email": "alice@example.com" },
{ "name": "Bob", "email": "bob@example.com" }
]
}💡Bulk resource creation payload accepting an array of items.
🎯 Interview Key Takeaway
Bulk API endpoints optimize throughput by processing arrays of items in a single HTTP request round-trip.
