Computer-implemented methods for synchronizing data between a server and a client are provided. In one aspect, a method includes receiving a request from a client to synchronize data. The request includes a synchronization token that includes client recent synchronization signatures, each client recent synchronization signature representing a state of data synchronization on the client for a certain time period. The method also includes comparing each client recent synchronization signature with a corresponding server recent synchronization signature representing data on a server for the same time period. When the comparison indicates that the data on the client for the time period represented by the client recent synchronization signature is not synchronized with corresponding data on the server for the time period, then the method includes sending the data on the server for the time period to the client. Systems and machine-readable media are also provided.

Data synchronization with eventual consistency

One embodiment of the invention is a method for storing transformed vertex attributes that includes the steps of allocating memory space for a transform feedback buffer, selecting one or more transformed vertex attributes to store in the transform feedback buffer independently of any shader programs executing on any processing units in the graphics rendering pipeline, configuring the transform feedback buffer to store the one or more transformed vertex attributes, and initiating a processing mode wherein vertex data is processed in the graphics rendering pipeline to produce the transformed vertices, the attributes of which are then written to the transform feedback buffer. One advantage is that the transform feedback buffer can be used to store and access transformed vertices, without having to convert the vertex data to a pixel format, store the pixels in a frame buffer, and then convert the pixels back to a vertex format.
