# SamplingTargetDocument
<a name="API_SamplingTargetDocument"></a>

Temporary changes to a sampling rule configuration. To meet the global sampling target for a rule, X-Ray calculates a new reservoir for each service based on the recent sampling results of all services that called [GetSamplingTargets](https://docs.aws.amazon.com/xray/latest/api/API_GetSamplingTargets.html).
