Method for reading data based on data cache technology

Abstract

The invention discloses a method for reading data based on a data cache technology. According to the method, by adopting an internal memory cache mechanism, user characteristic data corresponding users in a cache region are divided into different active levels according to vitality values, a chain table corresponding to each active level is established, a header of each chain table is marked, and the header of the chain table with the low active level points to the tail of the chain table with the relatively high active level, so that when data is read by many users, the user characteristic data to be accessed can be searched through the header of the chain table with the marked header, the data is read from an internal memory in a point-to-point manner, the consumption of loading the data from a database is reduced, the data loading speed is improved, the load of the database is lowered, and the user experience is promoted; meanwhile, a load of an input / output (IO) port is reduced by unoccupied internal memory, and the use of server hardware resources is balanced.

Description

technical field [0001] The invention relates to database cache technology, in particular to a method for reading data based on the data cache technology. Background technique [0002] In the network, WEB applications use the memory object cache system as the buffer of the database (DB), load data into the memory, and change the slow database (DB) access into faster memory access to improve performance. [0003] After the online game is launched, there is often a large number of players flooding the server during prime time, and the database is overwhelmed, causing players to wait for a long time or frequently disconnect when logging in, which affects the user experience. Taking Massive Multiplayer Online Role-Playing Game (MMORPG) as an example for illustration, MMORPG is divided into two parts: client and server. Players connect through the Internet from the client and log in to the server before they can play the game. Player data is stored on the server side. After pla...

AI Technical Summary

Problems solved by technology

When a large number of players flood into the server, the reading efficiency of the database still cannot meet the needs of the players, making the players wait for a long time when logging in

[0005] Although upgrading the hardware can significantly improve the above problems, the high-performance hardware upgrade brings a large waste of resources and economic burden to the client.
