TiDB Cloud Release Notes in 2024

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

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.

  To access this feature, you must be in the Organization Owner or Organization Billing Admin role of your organization.

  For more information, see Manage budgets for TiDB Cloud.

July 9, 2024

General changes

• Enhance the System Status page to provide better insights into TiDB Cloud system health and performance.

  To access it, visit https://status.tidbcloud.com/ directly, or navigate via the TiDB Cloud console by clicking ? in the lower-right corner and selecting System Status.

Console changes

• Refine the VPC Peering page layout to improve the user experience for creating VPC Peering connections in TiDB Dedicated clusters.

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.

June 25, 2024

General changes

• TiDB 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:

  • Vector data types, vector index, and vector functions and operators.
  • Ecosystem integrations with LangChain, LlamaIndex, and JinaAI.
  • Programming language support for Python: SQLAlchemy, Peewee, and Django ORM.
  • Sample applications and tutorials: perform semantic searches for documents using Python or SQL.

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

• TiDB 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.

June 18, 2024

General changes

• Increase the maximum node storage of 16 vCPU TiFlash and 32 vCPU TiFlash for TiDB Dedicated clusters from 2048 GiB to 4096 GiB.

  This enhancement increases the analytics data storage capacity of your TiDB Dedicated cluster, improves workload scaling efficiency, and accommodates growing data requirements.

  For more information, see TiFlash node storage.

• Upgrade the default TiDB version of new TiDB Dedicated clusters from v7.5.1 to v7.5.2.

June 4, 2024

General changes

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

  This feature enables you to replicate your databases between TiDB 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.

• Introduce billing and metering (beta) for the TiDB Serverless columnar storage TiFlash.

  Until June 30, 2024, columnar storage in TiDB Serverless clusters remains free with a 100% discount. After this date, each TiDB Serverless cluster will include a free quota of 5 GiB for columnar storage. Usage beyond the free quota will be charged.

  For more information, see TiDB Serverless pricing details.

• TiDB Serverless supports Time to live (TTL).

May 28, 2024

General changes

• Google Cloud Taiwan (asia-east1) region supports the Data Migration feature.

  The TiDB Dedicated clusters hosted in the Google Cloud Taiwan (asia-east1) region now support the Data Migration (DM) feature. If your upstream data is stored in or near this region, you can now take advantage of faster and more reliable data migration from Google Cloud to TiDB Cloud.

• Provide a new TiDB node size for TiDB Dedicated clusters hosted on AWS and Google Cloud: 16 vCPU, 64 GiB

API changes

• Introduce TiDB Cloud Data Service API for managing the following resources automatically and efficiently:

  • Data App: a collection of endpoints that you can use to access data for a specific application.
  • Data Source: clusters linked to Data Apps for data manipulation and retrieval.
  • Endpoint: a web API that you can customize to execute SQL statements.
  • Data API Key: used for secure endpoint access.
  • OpenAPI Specification: Data Service supports generating the OpenAPI Specification 3.0 for each Data App, which enables you to interact with your endpoints in a standardized format.

  These TiDB Cloud Data Service API endpoints are released in TiDB Cloud API v1beta1, which is the latest API version of TiDB Cloud.

    For more information, see Set a CIDR for a region.

• TiDB Serverless users now have the capability to disable public endpoints for your clusters.

  For more information, see Disable a Public Endpoint.

• Data Service (beta) supports configuring a custom domain to access endpoints in a Data App.

  By default, TiDB Cloud Data Service provides a domain <region>.data.tidbcloud.com to access each Data App's endpoints. For enhanced personalization and flexibility, you can now configure a custom domain for your Data App instead of using the default domain. This feature enables you to use branded URLs for your database services and enhances security.

  For more information, see Custom domain in Data Service.
