	// Functional tests don't use dynamic config files. All settings get their default values
	// defined in common/dynamicconfig/constants.go.
	//
	// There are 4 ways to override a setting:
	// 1. Globally using this file. Every test suite creates a new test cluster using this overrides.
	// 2. Per test suite using FunctionalTestBase.SetupSuiteWithCluster() and WithDynamicConfigOverrides() option.
	// 3. Per test using FunctionalTestBase.OverrideDynamicConfig() method.
	// 4. Per specific cluster per test (if test has more than one cluster) using TestCluster.OverrideDynamicConfig() method.
	//
	// NOTE1: settings which are not really dynamic (requires server restart to take effect) can't be overridden on test level,
	//        i.e., must be overridden globally (1) or per test suite (2).
	// NOTE2: per test overrides change the value for the cluster, therefore, it affects not only a specific test, but
	//        all tests for that suite. The automatic cleanup reverts to the previous value and tests don't affect each other.
	//        But that means tests in the same suite can't be run in parallel. This is not a problem because testify
	//        doesn't allow parallel execution of tests in the same suite anyway. If one day, it is allowed,
	//        unique namespaces with overrides per namespace should be used for tests that require overrides.
