Concepts

The documents in this section describe higher level concepts in the Go CDK.

Using provider-specific APIs

It is not feasible or desirable for APIs like blob.Bucket to encompass the full functionality of every provider. Rather, we intend to provide a subset of the most commonly used functionality. There will be cases where a developer wants to access provider-specific functionality, such as unexposed APIs or data fields, errors, or options. This can be accomplished using As functions.

URLs

In addition to creating portable types via provider-specific constructors (e.g., creating a *blob.Bucket using s3blob.OpenBucket), many portable types can also be created using a URL. The scheme of the URL specifies the provider, and each provider implementation has code to convert the URL into the data needed to call its constructor. For example, calling blob.OpenBucket("s3blob://my-bucket") will return a *blob.Bucket created using s3blob.OpenBucket.
