Kill theSpinningWheel20x acceleration in loading and startup times of Apps

Golgi accelerates app startup and loading times by up to 20x by managing the complete process of data transport between apps and between apps and servers

• Golgi apps have no spinning wheel because Golgi pushes content to apps in the background and when users startup a Golgi app the content is fresh. Golgi apps are unlike other apps which download their new content on app startup and show the spinning wheel while downloading. This spinning wheel can take many seconds to a minute depending on wireless bandwidth and the size of content being retrieved.

• With changes in connection types and speeds and even broken connections Golgi’s layer ensures app contentisdeliveredbyacombinationofretryandpushnotification,againeliminatingtheloadingtime

struct Message{ // options of bool, byte, i16, i32 1:required string myMsg // i64, double, string} // easily extensible with backward compatibility service golgiExample{ Message Chat(1:Message myMsg2u)}

Golgi Definition File (Thrift based)

Message myMsg2u = new Message(); // creating new Message ObjectmyMsg2u.setMyMsg(“Hello World”); // setting content of messageString myFriend = “+16501234567”; // developer defined namespaceChat.sendTo(myChatReplyHandler, myFriend, myMsg2u); // Void with Asynchronous Response

Use of Class in Sender (Android Java)

Chat.RequestReceiver myChatHandler = new Chat.RequestReceiver(){ @Override public void receiveFrom(Chat.ResultSender resultSender, Message rxMsg) { System.out.println(rxMsg); // Print out received message Message myReply = new Message(); // Create reply myReply.setMyMsg(“Hello you!”); // Populate reply resultSender.success(myReply); // Send Reply with Success }};Chat.registerReceiver(myChatHandler()); // Register Handler with Golgi

Use of Class in Receiver (Android Java)
