Current Limiting

> **Note:** This feature has been **removed in version V3.3.3.0**. The documentation below is retained for reference for users on earlier versions.

## Overview

The Current Limiting feature controls the request rate (QPS) for key API endpoints to prevent traffic spikes from overwhelming the system in high-concurrency scenarios. The **default QPS limit** for application access is **40**.
