Embodiment Construction

[0017] The present invention provides a data caching method and system based on the java platform, which caches multiple data with the highest frequency of access in the java memory, and at the same time, stores the hot data in a first-in-first-out manner through the queue sequence, thereby alleviating the access pressure and at the same time , has better timeliness and improves user experience.

[0018] According to an embodiment of the present invention, the data caching method based on the java platform includes:

[0019] S1, in each data access, obtain the access frequency of each data in the massive data;

[0020] S2, filter out multiple data with the highest access frequency, and cache these data in the java memory.

[0021] According to an embodiment of the present invention, in step S2, a queue sequence is created in the java memory, and the top N data with the highest frequency of access are used as hot data, and put into the queue sequence in a first-in-first-out or...

Abstract

The invention discloses a data caching method based on a java platform and a system. Multiple data having highest access frequency are cached in a java memory, moreover, the hot data is stored according to the queue sequence in an FIFO mode, so access pressure is alleviated, relatively good timeliness is realized, and user experience is improved.

Description

technical field [0001] The invention relates to the field of data storage in e-commerce, in particular to a data caching method based on a java platform. Background technique [0002] In recent years, with the rise of e-commerce, the "shopping cart" in online shopping has become the most core transaction basic component of major e-commerce companies. The shopping cart is also the only way and hub for users to shop, and there is no room for any mistakes. The data access volume is huge, and there are irregular peaks. The stability of the "shopping cart" has also become one of the main goals pursued by the e-commerce enterprise system. Due to the many factors affecting the stability of the shopping cart, it integrates basic services and its own storage, and directly faces the shopping hub of the public network. The main basic services that support the shopping cart: products, promotions, users, and the storage of the shopping cart itself are all dynamic and real-time call serv...
