Problems solved by technology

[0009] The present invention aims to solve the above-mentioned problems that the above-mentioned relational database cannot directly run the SQL language in the OLAP scene of processing massive data after sub-database and sub-table, and the efficiency of multiple union online queries is not high, and the error rate is high. The purpose is to provide A kind of equipment, system, method and storage medium based on MMR optimized MySQL aggregated into PostgreSQL database

Abstract

The MySQL database is aggregated into a PostgreSQL database device, which is used to aggregate the source-side MySQL database into a target-side PostgreSQL database after sub-databases. It is characterized in that it includes: a pre-setting part; a multi-source asynchronous replication part; Aggregation Department; Data Extraction Department; Full Volume Synchronization Department; SQL Statement Generation Department; Data Consistency Verification Department. The present invention aggregates the MySQL databases or tables after sub-databases and sub-tables into PostgreSQL, so that MySQL databases that have adopted the relational database management system can be aggregated and converted into PostgreSQL databases, so that the query performance of the database in OLAP situations is better than that of the original The performance of MySQL database on OLAP is improved several times. The PostgreSQL aggregate library is obtained by aggregating the data (library) of the sub-database and sub-table. In this way, only one library needs to be queried and the query code of one library needs to be written, so the writing time of the query code can also be saved, and the operation is simple and convenient. Smooth use for database administrators.

Description

technical field [0001] The invention relates to the field of database conversion, in particular to a device, method and system for converting MySQL database aggregation into PostgreSQL. Background technique [0002] Today's data processing can be roughly divided into two categories: online transaction processing OLTP (on-line transaction processing), online analytical processing OLAP (On-Line Analytical Processing). OLTP is the main application of traditional relational databases, mainly for basic, daily transaction processing, such as bank transactions. OLAP is the main application of database systems, supporting complex analysis operations, focusing on decision support, and providing intuitive and easy-to-understand query results. [0003] Specifically, OLTP, also known as transaction-oriented processing system, its basic feature is that the customer's raw data can be immediately transmitted to the computing center for processing, and the processing result is given in a v...
