appconfigdata¶
Description¶
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 callingStartConfigurationSession , 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 anInitialConfigurationToken to be given to the session’s client and used the first time it callsGetLatestConfiguration for that session.
Warning
This token should only be used once in your first call toGetLatestConfiguration . Youmust use the new token in theGetLatestConfiguration response (NextPollConfigurationToken ) in each subsequent call toGetLatestConfiguration .When callingGetLatestConfiguration , your client code sends the most recentConfigurationToken value it has and receives in response:
NextPollConfigurationToken: theConfigurationTokenvalue to use on the next call toGetLatestConfiguration.NextPollIntervalInSeconds: the duration the client should wait before making its next call toGetLatestConfiguration. This duration may vary over the course of the session, so it should be used instead of the value sent on theStartConfigurationSessioncall.- The configuration: the latest data intended for the session. This may be empty if the client already has the latest version of the configuration.
Warning
TheInitialConfigurationToken andNextPollConfigurationToken should only be used once. To support long poll use cases, the tokens are valid for up to 24 hours. If aGetLatestConfiguration call uses an expired token, the system returnsBadRequestException .For more information and to view example CLI commands that show how to retrieve a configuration using the AppConfig DataStartConfigurationSession andGetLatestConfiguration API actions, seeRetrieving the configuration in theAppConfig User Guide .
