AppConfigData#
Client#
- class AppConfigData.Client#
A low-level client representing AWS AppConfig Data
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 callsGetLatestConfiguration
for that session.Warning
This token should only be used once in your first call to
GetLatestConfiguration
. You must use the new token in theGetLatestConfiguration
response (NextPollConfigurationToken
) in each subsequent call toGetLatestConfiguration
.When calling
GetLatestConfiguration
, your client code sends the most recentConfigurationToken
value it has and receives in response:NextPollConfigurationToken
: theConfigurationToken
value 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 theStartConfigurationSession
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.
Warning
The
InitialConfigurationToken
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
