Abstract

The invention provides a database sub-database sub-table strategy determination method and device; the method comprises the steps: predicting the total data volume in a target database through employing the historical data volume of a database table in the target database in combination with a data prediction model, and obtaining the change trend of the total data volume; determining a peak time point when the total data volume reaches a threshold value according to the change trend of the total data volume; periodically segmenting and dividing the historical data in the database table to obtain a plurality of groups of historical data corresponding to different division periods; for each division period, verifying each group of historical data corresponding to the division period to obtain a corresponding verification result; according to verification results corresponding to all the division periods, judging whether historical data in the database table is changed or not, and determining a database division and table division mode according to a judgment result; and according to the peak time point and the database-dividing and table-dividing mode, determining a database-dividing and table-dividing strategy of the target database, so that the design reasonability of the database-dividing and table-dividing strategy is improved, and stable operation of an application system is ensured.

Description

technical field [0001] The invention relates to the technical field of data processing, in particular to a method and a device for determining a database sub-database sub-table strategy. Background technique [0002] In the application and development of computer software technology, the use of database occupies an important part. With the long-term operation of the application system and the arrival of the information explosion, the database is becoming more and more bloated and affects the performance of the database. Therefore, it is necessary to divide the database into tables and databases to ensure the stable operation of the application system. [0003] At present, the method of sub-database and table sub-database is: in the development and design stage of the application system, the future data volume is estimated, and the database sub-database sub-table strategy is designed according to the estimated results, and the sub-database sub-table of the database is complet...
