---------------------------------------
Summary: Allow ConfigOptions to validate the configured value
Key: FLINK-6576
URL: https://issues.apache.org/jira/browse/FLINK-6576
Project: Flink
Issue Type: Wish
Components: Configuration
Reporter: Chesnay Schepler
Priority: Trivial
It is not unusual for a config parameter to only accept certain values. Ports
may not be negative, modes way essentially be enums, and file paths must not be
gibberish.
Currently these validations happen manually after the value was extracted from
the {{Configuration}}.
I want to start a discussion on whether we want to move this validation into
the ConfigOption itself.
