How about the operating cost of deploying and maintaining a TiDB cluster?

TiDB provides a few features and tools, with which you can manage the clusters easily at a low cost:

  • For maintenance operations, TiUP works as the package manager, which simplifies the deployment, scaling, upgrade, and other maintenance tasks.
  • For monitoring, the TiDB monitoring framework uses Prometheus to store the monitoring and performance metrics, and uses Grafana to visualize these metrics. Dozens of built-in panels are available with hundreds of metrics.
  • For troubleshooting, the TiDB Troubleshooting Map summarizes common issues of the TiDB server and other components. You can use this map to diagnose and resolve issues when you encounter related problems.
