func EngineVersionsMatch ¶

func EngineVersionsMatch(desiredEV, latestEV string) bool

EngineVersionsMatch returns true if desired and latest engine versions match and false otherwise precondition: both desiredEV and latestEV are non-nil this handles the case where only the major EV is specified, e.g. "6.x" (or similar), but the latest version shows the minor version, e.g. "6.0.5".

func GetTags ¶

func GetTags(
	ctx context.Context,
	sdkapi elasticacheiface.ElastiCacheAPI,
	metrics *metrics.Metrics,
	resourceARN string,
) ([]*svcapitypes.Tag, error)

GetTags retrieves the resource's associated tags.

func SyncTags ¶

func SyncTags(
	ctx context.Context,
	desiredTags []*svcapitypes.Tag,
	latestTags []*svcapitypes.Tag,
	latestACKResourceMetadata *ackv1alpha1.ResourceMetadata,
	toACKTags func(tags []*svcapitypes.Tag) acktags.Tags,
	sdkapi elasticacheiface.ElastiCacheAPI,
	metrics *metrics.Metrics,
) (err error)

SyncTags keeps the resource's tags in sync

NOTE(jaypipes): Elasticache's Tagging APIs differ from other AWS APIs in the following ways:

1. The names of the tagging API operations are different. Other APIs use the Tagris `ListTagsForResource`, `TagResource` and `UntagResource` API calls. RDS uses `ListTagsForResource`, `AddTagsToResource` and `RemoveTagsFromResource`.

2. Even though the name of the `ListTagsForResource` API call is the same, the structure of the input and the output are different from other APIs. For the input, instead of a `ResourceArn` field, Elasticache names the field `ResourceName`, but actually expects an ARN, not the cache cluster name. This is the same for the `AddTagsToResource` and `RemoveTagsFromResource` input shapes. For the output shape, the field is called `TagList` instead of `Tags` but is otherwise the same struct with a `Key` and `Value` member field.
