Research on the rapid synchronization method of master-slave database information based on online evaluation
The traditional synchronization method lacks real-time evaluation and analysis mechanism,and the synchronization effect is not good.Therefore,this paper proposes a fast synchronization method of master-slave database information based on on-line evaluation.The master database is responsible for handling the write operation and maintaining the latest data,and notifying the slave database to synchronize the data when it changes.The online evaluation tool is introduced to evaluate the synchronized data in real time.Taking the data processing acceleration ratio as the evaluation index,the data processing mode is adjusted,and the rapid synchronization process of database information is designed.The synchronization results are returned to the main data-base through the feedback mechanism to ensure the synchronization effect and quality.The experimental results show that the CPU utilization rate of this method is within a reasonable range,and it has better synchronization effect,and the probability of cumula-tive error distribution is small,which indicates that it can maintain high reliability in the process of information synchronization.
