TiDB Cloud Release Notes in 2023

This page lists the release notes of TiDB Cloud in 2023.

January 10, 2023

General changes

  • Optimize the feature of importing data from local CSV files to TiDB to improve the user experience for Serverless Tier clusters.

    • To upload a CSV file, now you can simply drag and drop it to the upload area on the Import page.
    • When creating an import task, if your target database or table does not exist, you can enter a name to let TiDB Cloud create it for you automatically. For the target table to be created, you can specify a primary key or select multiple fields to form a composite primary key.
    • After the import is completed, you can explore your data with AI-powered Chat2Query by clicking Explore your data by Chat2Query or clicking the target table name in the task list.

    For more information, see Import local files to TiDB Cloud.

Console changes

  • Add the Get Support option for each cluster to simplify the process of requesting support for a specific cluster.

    You can request support for a cluster in either of the following ways:

    • On the Clusters page of your project, click ... in the row of your cluster and select Get Support.
    • On your cluster overview page, click ... in the upper-right corner and select Get Support.

January 5, 2023

Console changes

  • Rename SQL Editor (beta) to Chat2Query (beta) for Serverless Tier clusters and support generating SQL queries using AI.

    In Chat2Query, you can either let AI generate SQL queries automatically or write SQL queries manually, and run SQL queries against databases without a terminal.

    To access Chat2Query, go to the Clusters page of your project, click your cluster name, and then click Chat2Query in the left navigation pane.

January 4, 2023

General changes

  • Support scaling up TiDB, TiKV, and TiFlash nodes by increasing the Node Size(vCPU + RAM) for TiDB Dedicated Tier clusters hosted on AWS and created after December 31, 2022.

    You can increase the node size using the TiDB Cloud console or using the TiDB Cloud API (beta).

  • Extend the metrics retention period on the Monitoring page to two days.

    Now you have access to metrics data of the last two days, giving you more flexibility and visibility into your cluster performance and trends.

    This improvement comes at no additional cost and can be accessed on the Diagnosis tab of the Monitoring page for your cluster. This will help you identify and troubleshoot performance issues and monitor the overall health of your cluster more effectively.

  • Support customizing Grafana dashboard JSON for Prometheus integration.

    If you have integrated TiDB Cloud with Prometheus, you can now import a pre-built Grafana dashboard to monitor TiDB Cloud clusters and customize the dashboard to your needs. This feature enables easy and fast monitoring of your TiDB Cloud clusters and helps you identify any performance issues quickly.

    For more information, see Use Grafana GUI dashboards to visualize the metrics.

  • Upgrade the default TiDB version of all Serverless Tier clusters from v6.3.0 to v6.4.0. The cold start issue after upgrading the default TiDB version of Serverless Tier clusters to v6.4.0 has been resolved.

Console changes

  • Simplify the display of the Clusters page and the cluster overview page.

    • You can click the cluster name on the Clusters page to enter the cluster overview page and start operating the cluster.
    • Remove the Connection and Import panes from the cluster overview page. You can click Connect in the upper-right corner to get the connection information and click Import in the left navigation pane to import data.
