Hi, Jingsong Yep, I'm using blink planner as the following approach.
EnvironmentSettings bsSettings = EnvironmentSettings.newInstance().useBlinkPlanner().inStreamingMode().build(); initPack.tableEnv = org.apache.flink.table.api.java.StreamTableEnvironment.create(initPack.env, bsSettings); While running the job, I can see one log from console. [main] INFO org.apache.flink.table.module.ModuleManager - Cannot find FunctionDefinition date_fromat from any loaded modules Why Flink cannot load the function definition? From what I can see, Flink 1.10 with blink-planner shall support this kind of function. At 2020-02-04 12:35:12, "Jingsong Li" <jingsongl...@gmail.com> wrote: Hi Sunfulin, Did you use blink-planner? What functions are missing? Best, Jingsong Lee On Tue, Feb 4, 2020 at 12:23 PM Wyatt Chun <wyattc...@gmail.com> wrote: They are two different systems for differentiated usage. For your question, why don’t give a direct try on Blink?

Many date functions and string functions can not be used in Flink. I want to know that when shall we use flink just as to use blink in the same way. -- Best, Jingsong Lee
