aderm commented on issue #4292: Improve ES query performance URL: https://github.com/apache/skywalking/pull/4292#issuecomment-581039237 Regarding the occasional failure of e2e, I checked the logs and found that the traces printed in org.apache.skywalking.e2e.SampleVerificationITCase #doRetryableVerification sometimes query size two, the expected value size is one.This will cause the test to fail. If the number of traces obtained by the query is 1, it will pass. Several times before the code has not changed, the overall e2e test passed again <img width="1053" alt="WX20200201-231644@2x" src="https://user-images.githubusercontent.com/2892433/73594327-61438c00-4548-11ea-91f7-206835ed7568.png";> @kezhenxu94 When executing concurrently, maybe this happen?
