Method and system for template information management

Abstract

The invention provides a template information management method and system. Under the condition of big template information contents and numerous query demands, an efficient query service can be provided; the synchronous operation and the concurrent problem after template change in distributed cluster deployment are supported; and data sources of a query template can be intelligently switched according to memory performance. The method comprises the steps that each server in a distributed cluster initializes templates in a database to a memory for template query and / or change; when a templatechange demand exists, the server changes the corresponding templates in the memory according to an obtained template change request and stores the changed templates in the database; and the changed templates are sent to other servers in the distributed cluster by utilizing a group communication component, and other servers in the distributed cluster change the corresponding templates in the memoryaccording to the changed templates, thereby synchronizing the changed templates to other servers in the distributed cluster.

Description

technical field [0001] The invention relates to the field of computer technology and software, in particular to a template information management method and system. Background technique [0002] With the continuous development of cluster technology, it is becoming more and more extensive to provide template information services in a distributed cluster manner. Taking the field of invoices as an example, roll-type VAT invoices can be issued in all regions of the country at present, but the invoice templates are different in each region. In addition, the number and models of invoice printers used in each region are large, which leads to different types of invoices in different regions. All printers need a separate set of adapted invoice templates to ensure accurate and effective invoice printing. Therefore, in the business process of issuing invoices, the invoice template service is deployed in a distributed cluster to provide an efficient way to obtain invoice templates. ...

Problems solved by technology

[0005] 2. Large query demand

When there are a large number of concurrent calls, the query performance will drop sharply;

[0006] 3. When the template information needs to be changed, there may be concurrent changes to the template information;

[0007] 4. Other machine service information is not synchronized when modifying the template

However, no matter whether the template is stored in the Redis cache or in the memory, the above problems cannot be completely solved:

[0009] If the template is stored in the Redis cache, the problem of template modification synchronization can be solved. However, since the content of the template information may be large, the performance will drop sharply when a large number of concurrent calls are made; if the template information is stored in the memory, it can be solved. The problem of performance degradation of a large number of concurrent calls, but it cannot solve the problem of information out of synchronization after modifying the template in the case of distributed deployment

In addition, the template is stored in the memory. When the number of accesses reaches a certain amount, the system performance will be affected. At this time, there is no corresponding downgrading solution, which will cause the entire template service to be unavailable.
