How many messages were there in the ACL service? Were there any issues with load balancing and load?

The number of messages in the ACL service depends on the specific implementation and system load. In high-load systems, the ACL (Access Control List) service can process thousands or even millions of requests per second, especially if it is responsible for real-time access rights verification.

Problems with load balancing and system load often occur if the service does not scale horizontally or if there are bottlenecks in the architecture, such as blocking operations or slow database access.

To address these issues, the following are used:

• Caching of access rights verification results
• Horizontal scaling of the service using load balancers
• Asynchronous request processing, if possible
• Optimization of storage and access to ACL data

Without specific data, it is difficult to say exactly, but such problems are encountered in large systems and require attention.
