##### slow-task-detector.check-interval

1 s

Duration

The interval to check slow tasks.

##### slow-task-detector.execution-time.baseline-lower-bound

1 min

Duration

The lower bound of slow task detection baseline.

##### slow-task-detector.execution-time.baseline-multiplier

1.5

Double

The multiplier to calculate the slow tasks detection baseline. Given that the parallelism is N and the ratio is R, define T as the median of the first N*R finished tasks' execution time. The baseline will be T*M, where M is the multiplier of the baseline. Note that the execution time will be weighted with the task's input bytes to ensure the accuracy of the detection if data skew occurs.

##### slow-task-detector.execution-time.baseline-ratio

0.75

Double

The finished execution ratio threshold to calculate the slow tasks detection baseline. Given that the parallelism is N and the ratio is R, define T as the median of the first N*R finished tasks' execution time. The baseline will be T*M, where M is the multiplier of the baseline. Note that the execution time will be weighted with the task's input bytes to ensure the accuracy of the detection if data skew occurs.
