Problems solved by technology

[0004] This solution is acceptable when the amount of output data is relatively small, but when the amount of output data continues to increase, the total output time consumption increases significantly, and the number of concurrent cache accesses increases, especially when concurrent accesses increase. At the same time, the cache is invalid, and the system may be down at any time

Abstract

The invention discloses a data output method and a data output device. The data output method comprises the following steps of: 1, acquiring a data output request, judging whether corresponding legal output data exist in a storage space, if the corresponding legal output data exist, transmitting the output data, otherwise, judging whether the corresponding legal output data exist in a data file preset in a preset server, if the corresponding legal output data exist in the data file, acquiring the output data from the data file, and transmitting the output data, otherwise, reading the output data from a database, transmitting the output data, and asynchronously updating the storage space and the data file according to the output data read from the database; and 2, judging whether the output data stored in the storage space and / or the data file are effective according to a cache time stamp and a hash table, if the output data stored in the storage space and / or the data file are ineffective, reading the corresponding output data from the database, and updating the storage space and / or the data file according to the output data read from the database, otherwise, ending the operation.

Description

technical field [0001] The invention relates to the field of computer technology, in particular to a data output method and device. Background technique [0002] In the prior art, ordinary webpages will reduce the output content as much as possible during processing to ensure a good user experience. However, when outputting a webpage with a large amount of data, for example, the amount of data output by group purchase navigation will vary with the group purchase business. The continuous expansion and gradual increase. How to ensure the high timeliness of data, reduce the output time, and ensure the high reliability of the system is an urgent problem to be solved. [0003] At present, in the prior art, when the amount of web page output data is relatively small, when the cache is read, the cache status will be judged. If it is invalid or does not exist, the database will be accessed to obtain new data, and the cache will be updated at the same time. [0004] This solution i...
