Abstract

The invention discloses a historical data cleaning method and device. The historical data cleaning method comprises the steps that a historical data cleaning procedure is started automatically according to preset system starting time, a cleaning strategy configuration file is acquired, and at least one cleaning task is generated according to the cleaning strategy configuration file; predicted processing time of each cleaning task is calculated according to the historical task processing time; at least one cleaning task in a queue of tasks to be allocated is allocated to an idle cleaning unit according to the predicted processing time, wherein the cleaning unit processes the cleaning tasks and outputs a processed state after each cleaning task is processed; whether processing is successful or not is judged according to the processing states, if not, the states of the cleaning tasks failing to be processed are changed into states to be allocated and put into the queue of tasks to be allocated and wait to be allocated again. Configuration files can be reused in all systems, and therefore the system development and maintenance cost can be reduced; multi-process concurrent processing is supported, and the data cleaning efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of data cleaning, in particular to a method and device for cleaning historical data. Background technique [0002] In the application system database in many fields, a large amount of data is added every day, and the stock data of the database shows a state of continuous growth. As the amount of data increases, if the scale of online data cannot be effectively controlled, the access efficiency of production data and the overall efficiency of application system operation will be affected. Therefore, it is necessary to scan application data regularly, and delete data that has exceeded a certain storage time and is no longer useful. [0003] For the cleaning of historical data, the current main method is as follows: create a configuration file, scan the records in the configuration file one by one, and delete the data in the table in the corresponding database. This method has the following disadvantages: ...
