tomncooper opened a new pull request, #918: URL: https://github.com/apache/flink-kubernetes-operator/pull/918
## What is the purpose of the change The operator currently allows the following syntax for defining flink version specific defaults: `kubernetes.operator.default-configuration.flink-version.v1_18.key: value` The problem with this is that, in many cases, these defaults should be applied to newer Flink versions as well, forcing config duplications. This PR introduces a new "greater than" syntax for config defaults, indicating that they should be applied to a given version and above: `kubernetes.operator.default-configuration.flink-version.v1_18+.key: value` In this case key:value would be applied to all Flink version greater or equal to 1.18, unless overridden for specific versions. ## Brief change log - Adds a new method `getRelevantVersionPrefixes`, to the `org.apache.flink.kubernetes.operator.config.FlinkConfigManager`, which identifies all Flink version default config prefix which are relevant to the currently specified Flink version. - Refactored the `FlinkVersion` enum to specify major and minor semver integers to facilitate quick look up of relevant Flink versions when parsing version strings. ## Verifying this change This change added tests and can be verified as follows: - Added additional tests in the `FlinkConfigManagerTest` class to cover the new Regex and `getRelevantVersionPrefixes` methods. - Updated the `testVersionNamespaceDefaultConfs` test in `FlinkConfigManagerTest` to test the greater than version behaviour. ## Does this pull request potentially affect one of the following parts: - Dependencies (does it add or upgrade a dependency): no - The public API, i.e., is any changes to the `CustomResourceDescriptors`: no - Core observer or reconciler logic that is regularly executed: yes ## Documentation - Does this pull request introduce a new feature? yes - If yes, how is the feature documented?
