--------------------------
Labels: needs-discussion (was: )
> Measure thread running time precisely
> -------------------------------------
>
> Key: KAFKA-8881
> URL: https://issues.apache.org/jira/browse/KAFKA-8881
> Project: Kafka
> Issue Type: Improvement
> Affects Versions: 2.4.0
> Reporter: huxihx
> Priority: Major
> Labels: needs-discussion
>
> Currently, the code uses `System.currentTimeMillis()` to measure timeout.
> However, many situations trigger the thread suspend such as gc and context
> switch. In such cases, the timeout value we specify is not strictly honored.
> Maybe we could use ThreadMXBean#getCurrentThreadUserTime to precisely measure
> the thread running time.
