**Issue Evaluation**
Category: `question` | Status: **Answered**
Consumer thread pool size in `rocketmq-spring-boot-starter` is configured
via `@RocketMQMessageListener` annotation attributes:
- `consumeThreadMin` — minimum consumer threads (default: 1)
- `consumeThreadMax` — maximum consumer threads (default: 64)
Example:
```java
@RocketMQMessageListener(
topic = "my-topic",
consumerGroup = "my-group",
consumeThreadMin = 5,
consumeThreadMax = 20
)
```
These map to the underlying `DefaultMQPushConsumer` thread pool settings.
