10 решенийConnection Management
Ensure applications properly close database connections when they are no longer needed.
Connection Pool Tuning
Adjust the maximum number of connections in the application's database connection pool to an appropriate level.
Resource Throttling
Configure background processes to use a limited amount of system resources to avoid impacting live operations.
Schedule Optimization
Reschedule maintenance, backups, and batch jobs to off-peak hours.
Load Balancing and Caching
Implement application-level caching or load balancing to distribute requests and reduce direct database pressure.
Application Code Review
Identify and refactor inefficient queries or code patterns that cause excessive database load.
Resource Scaling
Increase the CPU, RAM, or storage capacity of the database server or consider a more powerful instance type.
Performance Tuning
Optimize slow queries, add appropriate indexes, and tune database configuration parameters for better resource utilization.
Consider Index Types
Explore different index types (e.g., B-tree, hash, full-text) based on the nature of the queries and data.
Implement Covering Indexes
Create indexes that include all columns needed by a query to avoid table lookups.

Выявленные причины
Accidental Deletion or Data Modification
70%Human error during manual data operations, script execution, or application updates can lead to unintended data loss. This is often the most common cause of unexpected data disappearance.
Application Bugs or Logic Errors
60%Flaws in application code, particularly in data processing or deletion routines, can cause data to be removed incorrectly or prematurely. This can be subtle and hard to detect without thorough code review.
Automated Data Purging or Archiving
50%Scheduled jobs or automated processes designed to clean up old or irrelevant data might be misconfigured or malfunctioning, leading to premature data removal.
Database Corruption or Disk Issues
30%Underlying storage issues, hardware failures, or database corruption can lead to data loss. This is less common but can be catastrophic when it occurs.
