Troubleshoot common causes and fixes, including: optimizing connection or compression protocols during network delay, upgrading hardware or adjusting InnoDB parameters during resource bottlenecks, enabling parallel replication during single-thread playback (set slave_paralle

SQL Data Loss Prevention (DLP)

SQL Data Leakage Prevention (DLP) is a mechanism to prevent sensitive data such as user information and transaction records in the database from being illegally accessed, exported or deleted. The core lies in controlling internal permissions, identifying data flow, and discovering abnormal operations. 1. SQLDLP is a complete set of mechanisms, including identifying sensitive data, controlling access rights, monitoring data export behavior, automatic alarm or blocking abnormal operations; 2. Implementation methods include data classification and tagging, access control (RBAC/ABAC), database audit, real-time monitoring and alarm, and data desensitization; 3. When deploying, pay attention to policy flexibility, log retention time, application layer control, and periodic update of sensitive data definitions; 4. Recommended tools include Microsoft SQLServer audit Dynamic data mask
