Abstract: A data synchronization method, system and apparatus are provided. The method includes receiving a request including data to be uploaded, from a client, and responding to the request after data is successfully obtained from the client, and storing the obtained data. For data whose size is less than a threshold value, a synchronization request is sent to a standby server to request the standby server to store the data. Otherwise a second type work log, including information indicating that data that has not been synchronized, is generated and stored. Data whose size is greater than or equal to the threshold value is not synchronized immediately, but is recorded in the work log. In some cases, data whose size is less than the threshold value, but fails to be synchronized, is recorded in the work log. Synchronization of this data may be subsequently completed according to the work log, so that the synchronization of this data can avoid affecting synchronization of other data.

Abstract: An online system receives a request for a video to be presented by the online system to a target user. The online system determines whether to insert secondary content into the video. For such a determination, the online system identifies a position in the video for inserting secondary content. Further, the online system determines a loss score and a gain score. The loss score measures a loss of interaction by the target user if the secondary content were inserted. The gain score includes a monetary compensation to be received by the online system for inserting the secondary content at the identified position. The online system compares the loss score and the gain score. Based on the gain score offsetting the loss score, the online systems modifies the video by inserting the secondary content at the identified position and provides the modified video for display to the target user.
