Functions

func CheckAWSSigningConfig 

func CheckAWSSigningConfig(config AWSSigning) error

CheckAWSSigningConfig checks if the AWSSigning configuration is valid

func Load 

func Load(env string, configDir string, zone string, config interface{}) error

Load loads the configuration from a set of yaml config files found in the config directory

The loader first fetches the set of files matching a pre-determined naming convention, then sorts them by hierarchy order and after that, simply loads the files one after another with the key/values in the later files overriding the key/values in the earlier files

The hierarchy is as follows from lowest to highest 

base.yaml
    env.yaml   -- environment is one of the input params ex-development
      env_az.yaml -- zone is another input param

	// 1) "noop" will not do any forwarding.
	//
	// 2) "all-domain-apis-forwarding" will forward all domain specific APIs(worker and non worker) if the current active domain is
	// the same as "allDomainApisForwardingTargetCluster"( or "allDomainApisForwardingTargetCluster" is empty), otherwise it fallbacks to "selected-apis-forwarding".
	//
	// 3) "selected-apis-forwarding" will forward all non-worker APIs including
	// 1. StartWorkflowExecution
	// 2. SignalWithStartWorkflowExecution
	// 3. SignalWorkflowExecution
	// 4. RequestCancelWorkflowExecution

	// 7. ResetWorkflow
	//
	// 4) "selected-apis-forwarding-v2" will forward all of "selected-apis-forwarding", and also activity responses
	// and heartbeats, but not other worker APIs.
	//
	// "selected-apis-forwarding(-v2)" and "all-domain-apis-forwarding" can work with EnableDomainNotActiveAutoForwarding dynamicconfig to select certain domains using the policy.
	//
	// Usage recommendation: when enabling XDC(global domain) feature, either "all-domain-apis-forwarding" or "selected-apis-forwarding(-v2)" should be used to ensure seamless domain failover(high availability)
	// Depending on the cost of cross cluster calls:
	//
	// 1) If the network communication overhead is high(e.g., clusters are in remote datacenters of different region), then should use "selected-apis-forwarding(-v2)".
	// But you must ensure a different set of workers with the same workflow & activity code are connected to each Cadence cluster.
	//
	// 2) If the network communication overhead is low (e.g. in the same datacenter, mostly for cluster migration usage), then you can use "all-domain-apis-forwarding". Then only one set of
	// workflow & activity worker connected of one of the Cadence cluster is enough as all domain APIs are forwarded. See more details in documentation of cluster migration section.
	// Usually "allDomainApisForwardingTargetCluster" should be empty(default value) except for very rare cases: you have more than two clusters and some are in a remote region but some are in local region.
	Policy string `yaml:"policy"`
	// A supplement for "all-domain-apis-forwarding" policy. It decides how the policy fallback to  "selected-apis-forwarding" policy.
	// If this is not empty, and current domain is not active in the value of allDomainApisForwardingTargetCluster, then the policy will fallback to "selected-apis-forwarding" policy.
	// Default is empty, meaning that all requests will not fallback.
	AllDomainApisForwardingTargetCluster string `yaml:"allDomainApisForwardingTargetCluster"`
	// Not being used, but we have to keep it so that config loading is not broken
	ToDC string `yaml:"toDC"`
}

ClusterRedirectionPolicy contains the frontend datacenter redirection policy When using XDC (global domain) feature to failover a domain from one cluster to another one, client may call the passive cluster to start /signal workflows etc. To have a seamless failover experience, cluster should use this forwarding option to forward those APIs to the active cluster.
