Can you characterize Wildberries services as high load? What was the peak RPS?

Yes, the services at Wildberries can be characterized as high load, considering the scale and number of users. At peak times, the load reached several tens of thousands of RPS (requests per second) on certain critical services.

To handle such traffic volume, the following are used:

• Horizontal scaling of services
• Caching at various levels (CDN, Redis)
• Asynchronous task processing through queues
• Optimization of database queries

This ensures high availability and low latency even with a large number of simultaneous requests.
