Hi @lif123, can you provide your test program? According to our previous performance tests, using union all can effectively reduce the consumption of database connections and improve performance. For more details, you can refer - https://mp.weixin.qq.com/s/Mn9K-mn1P7oX0G5PorZRMw. Therefore, there must be sufficient tests to prove that there is a performance problem with union all before we consider adding a switch. -- This is an automated message from the Apache Git Service.
