TiDB Cloud Release Notes in 2024

This page lists the release notes of TiDB Cloud in 2024.

December 17, 2024

General changes

  • TiDB Cloud Serverless backup and restore changes

    • Support restoring data to a new cluster, providing greater flexibility and ensuring your current cluster's operations remain uninterrupted.

    • Refine backup and restore strategies to align with your cluster plan. For more information, see Back Up and Restore TiDB Cloud Serverless Data.

    • Apply the following compatibility policy to help you transition smoothly:

      • Backups created before 2024-12-17T10:00:00Z will follow the previous retention duration across all clusters.
      • The backup time of scalable clusters will retain the current configurations, while the backup time of free clusters will be reset to default settings.

December 3, 2024

General changes

  • Introduce the Recovery Group feature (beta) for disaster recovery of TiDB Cloud Dedicated clusters deployed on AWS.

    This feature enables you to replicate your databases between TiDB Cloud Dedicated clusters, ensuring rapid recovery in the event of a regional disaster. If you are in the Project Owner role, you can enable this feature by creating a new recovery group and assigning databases to the group. By replicating databases with recovery groups, you can improve disaster readiness, meet stricter availability SLAs, and achieve more aggressive Recovery Point Objectives (RPO) and Recovery Time Objectives (RTO).

    For more information, see Get started with recovery groups.

General changes

November 12, 2024

General changes

  • Add the pause duration limit for TiDB Cloud Dedicated clusters.

    TiDB Cloud Dedicated now limits the maximum pause duration to 7 days. If you do not manually resume the cluster within 7 days, TiDB Cloud will automatically resume it.

    This change applies only to organizations created after November 12, 2024. Organizations created on or before this date will gradually transition to the new pause behavior with prior notification.

    For more information, see Pause or Resume a TiDB Cloud Dedicated Cluster.

  • Datadog integration (beta) adds support for a new region: AP1 (Japan).

  • Support a new AWS region for TiDB Cloud Dedicated clusters: Mumbai (ap-south-1).

  • Remove support for the AWS São Paulo (sa-east-1) region for TiDB Cloud Dedicated clusters.

October 29, 2024

General changes

  • New metric: add tidbcloud_changefeed_checkpoint_ts for Prometheus integration.

    This metric tracks the checkpoint timestamp of a changefeed, representing the largest TSO (Timestamp Oracle) successfully written to the downstream. For more information on available metrics, see Integrate TiDB Cloud with Prometheus and Grafana (Beta).

    Refine the layout of the Cluster Size section on the Create Cluster and Modify Cluster pages for TiDB Cloud Dedicated clusters. In addition, the Cluster Size section now includes links to node size recommendation documents, which helps you select an appropriate cluster size.

July 23, 2024

General changes

  • Data Service (beta) supports automatically generating vector search endpoints.

    If your table contains vector data types, you can automatically generate a vector search endpoint that calculates vector distances based on your selected distance function.

    This feature enables seamless integration with AI platforms such as Dify and GPTs, enhancing your applications with advanced natural language processing and AI capabilities for more complex tasks and intelligent solutions.

    For more information, see Generate an endpoint automatically and Integrate a Data App with Third-Party Tools.

  • Introduce the budget feature to help you track actual TiDB Cloud costs against planned expenses, preventing unexpected costs.

    For more information, see Manage budgets for TiDB Cloud.

July 9, 2024

General changes

Console changes

July 2, 2024

General changes

  • Data Service (beta) provides an endpoint library with predefined system endpoints that you can directly add to your Data App, reducing the effort in your endpoint development.

    Currently, the library only includes the /system/query endpoint, which enables you to execute any SQL statement by simply passing the statement in the predefined sql parameter. This endpoint facilitates the immediate execution of SQL queries, enhancing flexibility and efficiency.

    For more information, see Add a predefined system endpoint.

  • Enhance slow query data storage.

    The slow query access on the TiDB Cloud console is now more stable and does not affect database performance.

  • TiDB Cloud Serverless supports vector search (beta).

    The vector search (beta) feature provides an advanced search solution for performing semantic similarity searches across various data types, including documents, images, audio, and video. This feature enables developers to easily build scalable applications with generative artificial intelligence (AI) capabilities using familiar MySQL skills. Key features include:

    For more information, see Vector search (beta) overview.

  • TiDB Cloud Serverless now offers weekly email reports for organization owners.

    These reports provide insights into the performance and activity of your clusters. By receiving automatic weekly updates, you can stay informed about your clusters and make data-driven decisions to optimize your clusters.

  • Release Chat2Query API v3 endpoints and deprecate the Chat2Query API v1 endpoint /v1/chat2data.

    With Chat2Query API v3 endpoints, you can start multi-round Chat2Query by using sessions.

    For more information, see Get started with Chat2Query API.

Console changes

  • Rename Chat2Query (beta) to SQL Editor (beta).

    The interface previously known as Chat2Query is renamed to SQL Editor. This change clarifies the distinction between manual SQL editing and AI-assisted query generation, enhancing usability and your overall experience.

    • SQL Editor: the default interface for manually writing and executing SQL queries in the TiDB Cloud console.
    • Chat2Query: the AI-assisted text-to-query feature, which enables you to interact with your databases using natural language to generate, rewrite, and optimize SQL queries.

    For more information, see Explore your data with AI-assisted SQL Editor.
