Metrics Relation Graph Helps DBAs Quickly Locate Performance Problems in TiDB
TiDB v4.0.7 introduced a new feature: the metrics relation graph. It helps users clearly see the relationship between different performance metrics in a database cluster and thus quickly locate the root causes of performance problems.
How to Migrate Data from Amazon Aurora MySQL to TiDB Cloud
This post introduces how to smoothly migrate data from Amazon Aurora MySQL to TiDB Cloud using Dumpling and TiDB Lightning.
TiDB 4.0: An Elastic, Real-Time HTAP Database Ready for the Cloud
At TiDB DevCon 2020, Max Liu, CEO at PingCAP, gave a keynote speech. He believes that today's database should be more flexible, more real-time, and easier to use, and TiDB, an elastic, cloud-native, real-time HTAP database, is exactly that kind of database.
Cluster Diagnostics: Troubleshoot Cluster Issues Using Only SQL Queries
TiDB 4.0 introduces cluster diagnostics, a built-in widget in TiDB Dashboard, which lets you diagnose cluster problems within a specified time range. You can summarize the diagnostic results and cluster-related load monitoring information in a diagnostic report.
TiDB Dashboard: Easier Troubleshooting for Distributed Databases
TiDB 4.0 introduces TiDB Dashboard, which provides various built-in widgets in a graphical interface that let you easily diagnose, monitor, and manage your clusters in one place. Now you can troubleshoot TiDB clusters more easily.
Pessimistic Locking: Better MySQL Compatibility, Fewer Rollbacks Under High Load
With improvements in stability and functionality in TiDB 4.0, we finally remove the experimental label for pessimistic locking, making it a generally available feature. See how pessimistic locking behaves in TiDB.
TiCDC: Replication Latency in Milliseconds for 100+ TB Clusters
TiDB 4.0 introduces TiCDC, an open-source feature that replicates TiDB's incremental changes to downstream platforms. It shows only millisecond replication latency for 100+ TB clusters.
SQL Plan Management: Never Worry About Slow Queries Again
This post introduces how SQL Plan Management helps the optimizer automatically select efficient execution plans to prevent performance regressions caused by unexpected plan changes.
Key Visualizer: Observe Distributed Databases to Discover the Unknowns
Key Visualizer is a visual diagnostic tool that makes it easier to troubleshoot distributed SQL databases. Users can observe system health, quickly find hotspots in the cluster, and gain deep insights into applications.
How to Back Up and Restore a 10-TB Cluster at 1+ GB/s
Backing up or restoring a large-scale distributed SQL database is a time-consuming task. Our upcoming TiDB 4.0 release will support Backup & Restore (BR), a distributed backup and restore tool, which lets you back up and restore data at 1+ GB/s for 10-TB data.
