caiconghui opened a new issue #4132: URL: https://github.com/apache/incubator-doris/issues/4132
In the statistical summation scenario, LongAdder(introduced by jdk1.8) has better performance than AtomicLong in high concurrency update scenario. And if we just want to keep get and set operation for variable to be atomic, just add volatile at the front of the variable is enough, use AtomicLong is a little heavy. ---------------------------------------------------------------- This is an automated message from the Apache Git Service.
