Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present invention more apparent, the embodiments of the present invention are further described in detail below with reference to the accompanying drawings. The exemplary embodiments and descriptions of the present invention are provided to explain the present invention, but not to limit the present invention. It should be noted that the embodiments and features of the embodiments in the present application may be arbitrarily combined with each other without conflict.
Description of related terms:
a unit: a self-contained collection which can satisfy the relevant operation of a business processing link divided by a certain class of business according to a certain dimension contains most key services required by the business processing link and data required to be processed by the unit.
The unit structure comprises: the unit is taken as a basic unit for deployment, and most key applications or functional modules required by guest services are deployed in the unit.
The disadvantages of the architecture shown in fig. 1 are further explained in conjunction with fig. 1 as follows:
1) Application servers among different fragments in a unit cannot be shared, special backup devices (normally idle state) of each fragment application server cluster and a database cluster need to be prepared at the same time, and high availability strategies at a fragment level and a unit level need to be prepared at the same time:
A. when a certain fragmentation application server cluster in the unit fails, the fragmentation application server cluster is switched to another corresponding fragmentation application server cluster which is prepared in advance in the backup unit and is specially used for backup by the access route;
B. and if the application server of the whole unit fails, switching all the fragmented application server clusters of the unit to all corresponding fragmented application server clusters which are prepared in advance in the backup unit and are specially used for backup.
2) Due to the high availability strategy, more devices need to be deployed correspondingly, and the cost is higher.
Taking 32 pieces of fragments in each unit as an example, the application server of each fragment needs at least 2 high available load guarantees, and then at least 64 application servers are needed in a unit, and in addition, 64 application servers need to be backed up in another unit, and in conclusion, each unit needs at least 128 application servers in total, especially for applications with not large traffic, since uniform number of fragments and units must be followed, it is more wasteful to deploy the device in this way.
The overall high availability deployment costs are high and the high availability strategy is complex.
As shown in fig. 2, the architecture shown in fig. 1 is modified as follows:
1) A new lightweight data routing device is provided:
the data routing device is deployed to the application servers in each unit, the application servers in the units are subjected to unified cluster processing, and all the fragments are commonly shared.
2) High availability policy changes:
the application servers in the unit become a unified cluster for processing, the high-availability strategy of different fragmentation application servers in the unit does not need to be considered independently, and the operation and maintenance cost is simplified.
The disaster recovery backup connection pipe among the units can directly multiplex the application server cluster of the other unit, and the disaster recovery backup server cluster does not need to be prepared in the other unit, so that the deployment cost is saved.
The beneficial effects include:
1) The traditional one-layer application server routing method based on the distributed architecture is changed into two-layer application server routing, and the inherent method that the traditional distributed deployment architecture application server and the database server are paired to form the SET is broken through.
2) The data routing is usually used in a database link or integrated in a database as a data access layer, the invention is integrated in an application server, SQL sentences are not analyzed, the complexity is greatly reduced, the lightweight class improvement efficiency is kept, and the data routing is not deployed as an independent node, so that the communication among network nodes in one layer is reduced.

The apparatus may be a computer device for executing the method, and may for example include a server, and may specifically be a server in an application server cluster as shown in fig. 2.

The data information query processing method is explained, and as shown in fig. 5, the configuration center functions to configure the content.
Whether the range of the transaction elements is within the order of hundreds of data can be determined by inquiring the state of the computing plug-in, namely if the range of the transaction elements is within the order of hundreds of data, the computing plug-in is not used; if the data exceeds a hundred data magnitude, then a computing plug-in is used.
It should be noted that the final step in fig. 5 is to update the cell state, thereby ensuring that the cell state is correct.
As shown in fig. 6, the unit 1 is taken over by the unit 2 for explanation:
