Ability to get the configured region for an SdkClient

[etspaceman]

We have a need to be able to pass meta-data like the Region in our data bodies in a programatic way. Unfortunately there is no way to retrieve the configured region today.

Describe the Feature

The ability to get the configured region for a given SdkClient. E.g.:

KinesisAsyncClient client = KinesisAsyncClient.builder().build();
Region region = client.getRegion()

Is your Feature Request related to a problem?

No

Describe alternatives you've considered

We considered using an ExecutionInterceptor for this but it would require too much of an overhaul to our library to implement this.

Hi @etspaceman can you give us more details about your use case?

I'm wondering why would you need to get the region of a client you've just configured.

[etspaceman]

In our case, we maintain libraries that wrap KinesisClient and KinesisAsyncClient and produce messages that contain both a data body and some headers that describe the data (e.g. a message type, the content encoding, etc). We are looking to add the region of the source to this data. We would like to be able to derive the value on behalf of the user.

We do not know how the clients were configured so I can't access that information. Also, the clients may be configured in a variety of ways, e.g environment variables, explicit configuration, etc.

@etspaceman thank you for providing more context. We've added this to our backlog.

Hi @etspaceman,

ServiceClientConfiguration was added to SdkClient which exposes client settings, including the configured region. This feature was implemented in v2.20.32. Therefore closing the request.
