@Generated(value="com.amazonaws:aws-java-sdk-code-generator") public interface AWSAppConfigDataAsync extends AWSAppConfigData
AsyncHandler can be used to receive
notification when an asynchronous operation completes.
Note: Do not directly implement this interface, new methods are added to it regularly. Extend from
AbstractAWSAppConfigDataAsync instead.
AppConfig Data provides the data plane APIs your application uses to retrieve configuration data. Here's how it works:
Your application retrieves configuration data by first establishing a configuration session using the AppConfig Data StartConfigurationSession API action. Your session's client then makes periodic calls to GetLatestConfiguration to check for and retrieve the latest data available.
When calling StartConfigurationSession, your code sends the following information:
Identifiers (ID or name) of an AppConfig application, environment, and configuration profile that the session tracks.
(Optional) The minimum amount of time the session's client must wait between calls to
GetLatestConfiguration.
In response, AppConfig provides an InitialConfigurationToken to be given to the session's client and
used the first time it calls GetLatestConfiguration for that session.
When calling GetLatestConfiguration, your client code sends the most recent
ConfigurationToken value it has and receives in response:
NextPollConfigurationToken: the ConfigurationToken value to use on the next call to
GetLatestConfiguration.
NextPollIntervalInSeconds: the duration the client should wait before making its next call to
GetLatestConfiguration. This duration may vary over the course of the session, so it should be used
instead of the value sent on the StartConfigurationSession call.
The configuration: the latest data intended for the session. This may be empty if the client already has the latest version of the configuration.

Data StartConfigurationSession and GetLatestConfiguration API actions, see Receiving the
configuration in the AppConfig User Guide.
ENDPOINT_PREFIXgetCachedResponseMetadata, getLatestConfiguration, shutdown, startConfigurationSessionFuture<GetLatestConfigurationResult> getLatestConfigurationAsync(GetLatestConfigurationRequest getLatestConfigurationRequest)
Retrieves the latest deployed configuration. This API may return empty configuration data if the client already has the latest version. For more information about this API action and to view example CLI commands that show how to use it with the StartConfigurationSession API action, see Receiving the configuration in the AppConfig User Guide.
Note the following important information.
Each configuration token is only valid for one call to GetLatestConfiguration. The
GetLatestConfiguration response includes a NextPollConfigurationToken that should
always replace the token used for the just-completed call in preparation for the next one.
GetLatestConfiguration is a priced call. For more information, see Pricing.
