<@U06TM7M40RK> 2024-12-24 19:47:08,251 [pool-4-thread-1] INFO c.d.m.d.throttle.KafkaThrottleSensor:157 - Throttle exponential backoff reset.
The log message you provided, Throttle exponential backoff reset, is related to the KafkaThrottleSensor component in DataHub. This message indicates that the exponential backoff mechanism for throttling has been reset.
In the context of Kafka and DataHub, throttling is used to manage the rate at which messages are processed to prevent overwhelming the system. The KafkaThrottleSensor is responsible for monitoring and controlling this rate by implementing a backoff strategy when certain thresholds are exceeded.
According to the https://github.com/datahub-project/datahub/blob/master/metadata-dao-impl/kafka-producer/src/main/java/com/datahub/metadata/dao/throttle/KafkaThrottleSensor.java|KafkaThrottleSensor.java, the backoff mechanism is used to delay processing when the system is under heavy load. The reset message suggests that the conditions that triggered the backoff have been resolved, and normal processing can resume.
If you need more detailed information about how the backoff mechanism works or how to configure it, please let me know!
