Upload Frequency

To save bandwidth, mParticle does not always immediately send each event as it is generated. Instead we upload batches of events according to set rules.

The SDK always uploads:

as soon as possible on the first session for a client, to ensure that install events are immediately available
whenever the app is sent to background
whenever a Commerce event is logged
whenever a session ends. This may be after a user navigates away from your app according to the configured session timeout

You can force an upload with the upload method.

Objective-CSwift

[[MParticle sharedInstance] upload];

MParticle.sharedInstance().upload()

If none of the above conditions occur, the SDK allows a maximum interval to elapse before the next upload. This interval is configurable, defaulting to every ten seconds in development, and ten minutes in production.

Objective-CSwift

// Assumes the SDK has been included as a dynamic library
// Requires "Enable Modules (C and Objective-C)" in pbxproj
@import mParticle_Apple_SDK; 

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {
    
    //initialize mParticle
    MParticleOptions *options = [MParticleOptions optionsWithKey:@"REPLACE WITH APP KEY"
                                                          secret:@"REPLACE WITH APP SECRET"];
    options.uploadInterval = 30;
    [[MParticle sharedInstance] startWithOptions:options];

    return YES;
}

import mParticle_Apple_SDK

func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplicationLaunchOptionsKey: Any]?) -> Bool {

    //initialize mParticle
    let options = MParticleOptions(key: "REPLACE WITH APP KEY",
                                         secret: "REPLACE WITH APP SECRET")
                                         
    options.uploadInterval = 30
    MParticle.sharedInstance().start(with: options)
        
    return true
}
