Writing the stage in the environment represents the rectangular space in Flash player, or the Web browser window that displays the file when it is played. To change the view of the stage as you work, enlarge or shrink the stage. Use grid lines, leader lines, and rulers to help you schedule items on the stage.

However, when the throughput is very high, disk I/O becomes a bottleneck, the solution is to use the cache to change random write to continuous write. Considering the status of the main operation data of zookeeper, Zookeeper proposes two security attributes (Safety Property) to ensure State consistency) Total order: If message a is sent before message B, all servers should see the same result.
