Online accidents (3)

The data cleaning operation occurs on the scene server. This cleaning operation is triggered by forwarding the message through the function server. Before the message is triggered, if the player jumps to the scene server faster than the message trigger speed, they can repeatedly claim rewards. The root cause of this problem is that there is no waiting for the function server to return to confirm that the data cleaning is completed before performing the operation, but the player jumps to the scene is also unpredictable, so there is no way to wait, only the trigger process of the data cleaning can be set on the scene server. It is not triggered by forwarding the message to the functional server, or the data is only stored on the scene server that needs to be used, not all the scene servers.
