Problems solved by technology

[0004] Since the data copies cached in the prior art are all complete sets, the cache system has no horizontal scalability. As the total amount of cached data increases, memory resources will become a bottleneck, resulting in poor horizontal scalability of the cache system.

Embodiment Construction

[0047] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0048]The embodiment of the present invention discloses a caching method and system for air freight rate data. Firstly, the air freight rate data is converted into the data format of the first-level cache and stored in the first-level cache, and then the air freight data stored in the first-level cache is Price data, data sharding based on flight departure city and flight destination city to generate shard data, where each data node of shard data contains a cop...

Abstract

The invention discloses a caching method and system for air freight rate data. Firstly, the air freight rate data is converted into the data format of the first-level cache, and stored in the first-level cache, and then the air freight rate data stored in the first-level cache is , based on the flight departure city and the flight destination city, the fragmented data is generated by data fragmentation. Each data node of the fragmented data contains a copy of the complete data set of the air freight rate data for which the fragmentation algorithm is not available and a copy of the available fragmentation algorithm. The data subsets of air freight rate data, each data subset constitutes the data set of air freight rate data that can be fragmented, and the fragmented data is stored in the secondary cache after it takes effect. Since each data node of the fragmented data cached to the secondary cache only contains part of the air freight data available with the fragmentation algorithm, the present invention improves the It improves the horizontal expansion capability of the cache system.

Description

technical field [0001] The present invention relates to the technical field of air transport information, more specifically, to a caching method and system for air freight rate data. Background technique [0002] With the rise of Internet technology and the rapid development of the online travel market, online booking and purchase of air tickets has become the first choice for many travelers. However, massive air ticket search and booking requests, as well as the demand for air ticket prices to be released and effective in real time, have brought new challenges to the freight rate calculation system and the freight rate search system. [0003] When performing data caching in the prior art, all effective data is first exported from the database, and the data files are generated and compressed, and then the compressed data files are distributed to the data node hosts of each caching service by using the data distribution network; when each data agent (A background program) Af...
