Air ticket inquiring cache method

Abstract

The invention discloses an air ticket inquiring cache method which includes the steps: inquiry statistics; query cache; cache checking; cache updating; active caching. According to the method, characteristics of air ticket business are considered based on active caching and passive caching, cache updating and adjustment of cache control parameters are combined, cache is timely updated, cache data accuracy is high, cache hit ratio is high, calling frequencies of external interfaces are effectively reduced, cost is controlled, and the method is different from a past method that control parameters and statistic data are adjusted by taking experience values as standards. According to the method, dynamic adjustment is achieved according to actual states, statistic is performed in real time, and timely and effective feedback is achieved.

Description

technical field [0001] The invention belongs to the technical field of data cache, and relates to an air ticket query control method. Background technique [0002] The air ticket resource supply system is used to connect downwards with external supply interfaces such as airlines, and provide unified standard query services upwards. Query cache is usually required in the air ticket resource supply system. There are two main reasons: First, the performance of the external interface that the data source depends on is uneven, the response time is long and affects the customer experience, and the query result needs to be cached to achieve response within the settling time. Second, the supplier has strict requirements on the number of calls to the interface, such as charging per use, charging according to the ratio of query and ticket issuance, etc. Therefore, the number of calls (cost) to the external interface must be controlled within a reasonable range through caching.

Problems solved by technology

[0006] Aiming at the problems of untimely update, low accuracy, high cost of calling interface, low hit rate of passive caching method and uncontrollable cache expiration time in the existing active caching method, the present invention discloses a general query caching method for ticket business, which takes into account the active On the basis of passive caching, combined with the characteristics of the ticket business, the cache update is combined with the adjustment of cache control parameters to ensure timely cache update, high cache data accuracy, high cache hit rate, and good cost control
