Hi @feizhangyong - feel free to submit a PR if you have a fix for this issue ready!

@willarmiros sorry ,not fix it ①BatchBaseApplication.java AWSXRayRecorderBuilder builder = AWSXRayRecorderBuilder.standard().withDefaultPlugins().withSamplingStrategy(new NoSamplingStrategy()).withSegmentListener(new SLF4JSegmentListener());

②log is too long ,so i change the log

these log are changed, sizes are ok

③after endSegment, segment.subsegmentsList　sizes also be too long why?

[feizhangyong]

trace map and trace logs can be see,

The log (too long) part is not output to trace log

If you are getting subsegment too long errors, it is likely because the metadata you are adding is too big to fit into a UDP socket which is 64 KB. I would suggest removing or trimming the metadata you're adding to be less than 64 kB.

thank you control →service → logic　 parent son grandson

add this, Asserting Parent-Child Relationships of Classes

@Override
protected Object processXRayTrace(ProceedingJoinPoint pjp) throws Throwable {
    Subsegment subsegment = AWSXRay.beginSubsegment(pjp.getSignature().getDeclaringTypeName() + "." + pjp.getSignature().getName());
    **subsegment.setParentId(subsegment.getParentSegment().getId());**

UDPEmitter overwrite it loop Subsegment, Iterator iterator = subsegment.getSubsegments().iterator(); while (iterator.hasNext()) { Subsegment childSubsegment = iterator.next(); sendSubsegment(childSubsegment); iterator.remove();

→After the top-level response is completed, it is possible to resolve this issue.
