What It Is
In data engineering it is usually measured in events, messages, or requests per second. One million events per second is a throughput of one million events per second. It is a core measure of capacity alongside latency.
Key Points
- Versus latency: latency measures how long each operation takes.
- Batching: raises throughput but can add delay per item.
- Bottlenecks: the slowest component, such as network, storage, or one partition, sets the limit.
- Methods: load testing and profiling reveal bottlenecks.
Why It Matters
Improving throughput can affect latency, so both must be balanced. Real systems are limited by their slowest part, so scaling out or redesigning data flows often matters more than tuning one component.
How ClearLeaff Applies It
We build pipelines and backends that sustain more than one million events per second at low latency, validating targets with realistic load tests and monitoring after launch.
