System Design Interview: Throughput vs. Latency (The Trade-Off No One Explains)

Описание: System Design Interview: Throughput vs. Latency (The Trade-Off No One Explains)

If you ask a Junior Engineer the difference between Throughput and Latency, they will give you a textbook definition. If you ask a Software Architect, they will tell you about the War.

In this video, we clarify one of the most fundamental concepts in System Design in just 2 minutes. We explain why "maximizing performance" is a myth because in real-world distributed systems, Throughput and Latency fight each other.

In this video, we cover:
• The Definitions: Why "Latency is speed" and "Throughput is capacity."
• The Conflict: Why increasing throughput (handling 200 more customers) almost always ruins latency (everyone waits longer for food).
• The Queue Effect: How buffering requests to save the system creates the "wait time" that kills user experience.

• Real-World Trade-offs:
◦ Redis: Optimized for Latency (Single request speed).
◦ Kafka: Optimized for Throughput (Batching massive volume).
◦ Payment Systems: Optimized for Correctness (ignoring both).

The Interview Answer: Don't just define the terms. We give you the exact script to say in an interview to prove you understand how systems break under load.
