Creating Additional Subsegments

In the user model class, the application manually creates subsegments to group all downstream calls made within the saveUser function and adds metadata.

Example src/main/java/scorekeep/ - Custom Subsegments

import com.amazonaws.xray.AWSXRay; import com.amazonaws.xray.entities.Subsegment; ... public void saveUser(User user) { // Wrap in subsegment Subsegment subsegment = AWSXRay.beginSubsegment("## UserModel.saveUser"); try {; } catch (Exception e) { subsegment.addException(e); throw e; } finally { AWSXRay.endSubsegment(); } }
