Hi all, Xuannan(cced) and I would like to start a discussion on FLIP-405: FLIP-405: Migrate string configuration key to ConfigOption[1].
As Flink progresses to 2.0, we want to enhance the user experience with the existing configuration. In FLIP-77, Flink introduced ConfigOption with DataType and strongly encourage users to utilize ConfigOption instead of string keys for accessing and setting Flink configurations. Presently, many string configuration keys have been deprecated and replaced with ConfigOptions; however, some string configuration keys are still in use. To ensure a better experience with the existing configuration in Flink 2.0, this FLIP will migrate all user-facing string configuration keys to ConfigOptions. Additionally, we want to modify the Configuration infrastructure to promote the use of ConfigOption over string configuration keys among developers and users. It's mentioned in a preview thread[2]. Looking forward to everyone's feedback and suggestions, thank you! [1] https://cwiki.apache.org/confluence/x/6Yr5E [2] https://lists.apache.org/thread/zzsf7glfcdjcjm1hfo1xdwc6jp37nb3m Best, Rui
