Your company's database is experiencing slow query performance during peak usage hours. How would you troubleshoot and optimize the queries to maintain optimal performance levels?

  • Analyze query logs and execution times, Identify and resolve blocking queries, Optimize database indexes, Consider query caching
  • Backup and restore the entire database, Optimize only the most frequently used queries, Ignore query logs, Add more indexes without analysis
  • Disable query caching, Increase server memory, Use NoSQL instead of SQL, Optimize the network configuration
  • Reboot the database server, Purge all old records, Increase the database security, Change the database schema
Troubleshooting slow query performance involves analyzing query logs, execution times, and identifying/resolving blocking queries. Optimizing indexes and considering query caching are effective strategies to maintain optimal performance during peak hours.
