Problems solved by technology

[0004] Even if the memory can handle messages containing such a large transaction, according to the current implementation mechanism, SPM and SAM will start subsequent processing after receiving the entire transaction, so that the entire data synchronization process is equivalent to serial processing. It will also have a great impact on data synchronization performance

Abstract

The invention provides a message-based event application device, which is used for enabling incremental data manipulation statements applied to a first data source to be synchronously applied to a second data source, and comprises a dividing unit and an application unit, wherein the dividing unit is used for obtaining the incremental data manipulation statements from the first data source and packeting the incremental data manipulation statements according to transactions, judging whether the transactions are events, dividing the events into multiple parts and sending a message formed by the incremental data manipulation statements in each part into the application unit; and the application unit is used for creating local transactions of the second data source and corresponding application tasks when receiving the message, so that the application tasks apply the incremental data manipulation statements in the message to the second data source based on the local transactions. The invention further provides a message-based event application method. According to the technical scheme, synchronism of real-time incremental data can be improved.

Description

technical field [0001] The invention relates to the technical field of data synchronization, in particular, to a message-based large-scale transaction application device and method. Background technique [0002] exist figure 1 In the shown data synchronization schematic diagram, at first, the incremental data extraction module (SEM) 102 extracts the incremental operation from the OLTP data source, and at the same time, basic analysis and transaction classification are performed on these data, and then they are packaged and transmitted to The data conversion module (SPM) 104, after receiving the packaged transaction, the data conversion module (SPM) 104 converts the SQL operation of the transaction as required, and notifies the data application module (SAM) 106 to apply the transaction after the processing is completed. In order to ensure the absolute reliability of the incremental synchronization of the entire data, a transmission platform (such as message middleware, etc.)...
