Fig. 1 is a schematic application scenario diagram of a method for real-time data synchronization according to an embodiment of the present application. As shown in fig. 1, the application scenario includes a server 20 and a server 30; the server 20 and the server 30 may be servers, server clusters, or cloud computing centers, and the server 20 and the server 30 belong to different systems. The server 20 and the server 30 can perform data synchronization with each other.
As shown in fig. 2, the present embodiment provides an electronic apparatus 1 including: at least one processor 11 and a memory 12, one processor 11 being exemplified in fig. 2. The processor 11 and the memory 12 are connected by a bus 10, and the memory 12 stores instructions executable by the processor 11, and the instructions are executed by the processor 11, so that the electronic device 1 can execute all or part of the flow of the method in the embodiments described below. In an embodiment, the electronic device 1 may be the server 20 or the server 30, and is used for performing a method of real-time data synchronization.
The Memory 12 may be implemented by any type of volatile or non-volatile Memory device or combination thereof, such as Static Random Access Memory (SRAM), Electrically Erasable Programmable Read-Only Memory (EEPROM), Erasable Programmable Read-Only Memory (EPROM), Programmable Read-Only Memory (PROM), Read-Only Memory (ROM), magnetic Memory, flash Memory, magnetic disk or optical disk.
The present application also provides a computer readable storage medium storing a computer program executable by the processor 11 to perform the method for real-time synchronization of data provided herein.
Referring to fig. 3, a flow chart of a method for real-time data synchronization according to an embodiment of the present application is shown, and as shown in fig. 3, the method may include the following steps 310 to 330.
Step 310: and when target data is newly added or updated in the database, calling a preset storage process script through a preset trigger.
The target data refers to newly added data and updated data in the database.
The Stored Procedure script may be a pre-compiled script that is Stored in a database to implement storage. The stored procedure script can be used for writing the data in the database into the service of the application layer of the server.
When the target data is newly added to the database on the server side, or when the target data is updated in the database on the server side, a trigger preset on the server side is triggered, and at the moment, the server side can call the stored process script through the trigger. And when the server calls the stored process script through the trigger, the target data can be transmitted to the stored process script.
Step 320: and calling a preset interface adapter through the stored procedure script.
The interface adapter is a data transmission script of a server application layer, and the interface adapter is configured with a corresponding data transmission position in advance.
After the server calls the stored process script through the trigger, the server calls the interface adapter through the stored process script, so that the target data is transmitted to the interface adapter, and the interface adapter of the application layer can transmit the target data.
Step 330: and transmitting the target data to the opposite-end system through the interface adapter.
The peer system shares data with the system where the server executes the steps 310 to 330.
The server side can write the target data into a pre-configured data transmission position through the interface adapter, so that the target data is transmitted to the opposite end system, and real-time synchronization of the data is realized.
According to the scheme, when the database inserts data or updates the data, the pre-configured trigger can be triggered, the stored process script is called, and the target data is transmitted to the application layer of the server from the database. After the interface adapter is called through the stored procedure script, the interface adapter can transmit the target data to the opposite terminal system. The trigger can be triggered immediately after the target data appears to call the stored process script, and then the target data is transmitted to the opposite terminal system through the interface adapter in the subsequent process, so that the real-time performance and the safety of data transmission are ensured.
In an embodiment, when the server executes step 330, a specified service interface of the peer system may be called by the interface adapter, so that the specified service interface may obtain the target data. The specified service interface is an HTTP (HyperText Transfer Protocol) service interface which is open to the outside of the peer system and used for writing data.
After the opposite-end system obtains the target data through the appointed service interface, the target data can be written into a local message queue, and after the target data is read from the message queue, the target data is written into a local data warehouse. The message queue can be any one of message queues such as ActiveMQ, RabbitMQ, Kafka and RockketMQ, and the message queue is positioned in a peer system.
In an embodiment, the system where the server executes steps 310 to 330 directly transmits the target data with the peer system through the message queue, and the peer system does not need to develop a specific service interface. When the server executes step 330, the target data may be written into a specified message queue interfaced with the peer system through the interface adapter. Wherein the specified message queue is a message queue for transmitting messages to the peer system. The specified message queue may be located on a peer system, a server system, or a third party server. After the opposite-end system acquires the new message through the appointed message queue, the target data can be analyzed from the new message, and the target data is written into a local data warehouse.
In an embodiment, a home system where a server is located may have multiple peer systems, and data synchronized by the home system is different from data synchronized by different peer systems. In this case, a plurality of triggers may be preconfigured on the server, and stored procedure scripts and interface adapters corresponding to each trigger.
When the target data is newly added or updated in the database, the server can judge whether the target data meets a preset data synchronization strategy. The server can be configured with a plurality of data synchronization strategies, each data synchronization strategy corresponds to at least one opposite-end system, and the data synchronization strategies are used for screening data transmitted to the opposite-end systems.
When the target data meets any data synchronization strategy, the trigger corresponding to the data synchronization strategy is triggered, and the server side can use the stored process script corresponding to the data synchronization strategy through the trigger corresponding to the data synchronization strategy. For example, the data synchronization policy may be to transmit the target data to a specified peer system when a specified field of the target data satisfies a preset condition. Such as: the consumption record of the game player is recorded in the database, the designated field can be the single recharging amount of the player, the designated opposite-end system can be the game marketing system, and when a consumption record is newly added, if the single recharging amount in the consumption record is larger than 100 yuan, the consumption record can be transmitted to the game marketing system. For another example: the database records the website browsing records of the news website, the designated field can be time period and column name, the designated opposite-end system can be a website optimization system, and when one browsing record is newly added, if the time period of the browsing record is 7-point-half to 9-point and the column name is 'domestic information', the browsing record can be transmitted to the website optimization system.
The subsequent server side can call the interface adapter corresponding to the data synchronization strategy through the storage process script, so that the target data is transmitted to the opposite end system corresponding to the data synchronization strategy through the interface adapter.
By the measures of the embodiment, the corresponding target data can be transmitted to different opposite-end systems according to different data synchronization strategies, and real-time data synchronization to different opposite-end systems is realized.
