Abstract

The invention discloses a method and a device for traversing a timer, relates to the technical field of the Internet and is invited for solving the low traversing efficiency of the timer. The method comprises the following steps: constructing a timer binary tree, wherein the node numerical value of the timer binary tree is the arrival time moment value of the timer, the subnode of which the node numerical value is greater than a father node numerical value is the right subnode of the father node, and the subnode of which the node numerical value is smaller than the father node numerical value is the left subnode of the father node; traversing from a root node, and searching a target node of which the node numerical value is smaller than or equal to a current moment value; and closing the timer corresponding to the target node. The method is mainly used for traversing the timer used by a server memory.

Description

technical field [0001] The invention relates to the technical field of the Internet, in particular to a method and device for traversing a timer. Background technique [0002] When the terminal requests data from the server, the server will access the database, obtain the data content requested by the terminal from the database and return it to the terminal. Since each request will access the database, when the number of concurrent requests is large, it will cause a relatively large access pressure on the database. In order to reduce the access pressure of the database, engineers improved the existing technology and cached the data obtained from the database in the server memory. When the terminal initiates a data request, the server searches the memory for the data requested by the terminal, and returns it directly to the terminal if the data is found, thereby reducing the number of visits to the database. [0003] Usually, server-side memory resources are very precious, ...
