How to use 'Transaction Log'?

[LiJie20190102]

I created a test using ‘Transaction Log’, but it did not meet my expectations. Is there a problem with my usage?
232 lines have no execution effect.

Log processor runs in a separate thread. Try adding a Thread.sleep before the test exits.

Try increasing to 30 seconds?

[LiJie20190102]

60 seconds still has no effect ,Please help me check if there are any issues with the code

Please post your full code here

@test
public void testLogTransaction() throws InterruptedException {

  StandardJanusGraph g = (StandardJanusGraph)ConfiguredGraphFactory.open("graph_test2");


  JanusGraphTransaction start =
      g.buildTransaction().checkExternalVertexExistence(false).logIdentifier("addedPerson").start();

  // vertices
   start.addVertex(T.id, "lisi2", T.label, "people","name","aaaaa");
  start.commit();
  System.out.println("=============ok");

  LogProcessorFramework logProcessor = JanusGraphFactory.openTransactionLog(g);

  logProcessor.addLogProcessor("addedPerson").
      setProcessorIdentifier("addedPersonCounter").
      setStartTime(Instant.MIN).setRetryAttempts(1).
      addProcessor(new ChangeProcessor() {
          @Override
          public void process(JanusGraphTransaction tx, TransactionId txId, ChangeState changeState) {
              Set<JanusGraphVertex> vertices = changeState.getVertices(Change.ADDED);
              for (JanusGraphVertex vertex : vertices) {
                  if (vertex.label().equals("people")) {
                      System.out.println("vertex==1=="+vertex);
                  }
              }
          }
      }).
      build();

  Thread.sleep(60000);

}

weird, I haven't used this feature for a long time but I have used it in production before...

@li-boxuan
Meanwhile, in (https://docs.janusgraph.org/advanced-topics/janusgraph-bus/), I noticed that there seems to be a different explanation for 'Transaction Log' and instead recommended me to use 'Trigger Log'. I'm a bit confused. Is there a more detailed introduction?

This is a known issue: #3128

You could pretty much ignore what janusgraph-bus said.

[LiJie20190102]

Okay, based on the code (#4333 (reply in thread)) I provided, have you found the reason why it cannot take effect

[li-boxuan]

Nope... I suggest you ask in the mailing list

[li-boxuan]

There's also a test in JanusGraphTest.java. You might want to use debugger to test that.

Okay, an email has been sent for assistance. I referred to org.janusgraph.graphdb.JanusGraphTest#simpleLogTestWithFailure, but I didn't get the result I wanted either
