When using Flink 1.9.3 with Blink Planner, I tried to union some tables with Chinese constants and get an OutOfMemoryError of Java heap space. Here are the code and the error message.
I turned to the old planner and it works. Then I upgraded Flink to 1.11.2 and it also works. Also, it does work when I remove either 'union all' or Chinese words. I searched JIRA and found FLINK-16113 <https://issues.apache.org/jira/browse/FLINK-16113> with some bugfix of Chinese words, but what about the memory? And what about union all? *Code in Flink 1.9.3:* *Error Message:* *Code in Flink 1.11.2 with some new syntax:* ----- Best wishes.
