This page lists the release notes of TiDB Cloud in 2022.

October 19, 2022

Integration changes

October 18, 2022

General changes

  • For Dedicated Tier clusters, the minimum storage size of a TiKV or TiFlash node is changed from 500 GiB to 200 GiB. This will be more cost-effective for users whose workloads are in small data volumes.

    For more details, see TiKV node storage and TiFlash node storage.

  • Introduce online contracts to customize TiDB Cloud subscriptions and meet compliance requirements.

    A Contract tab is added to the Billing page of the TiDB Cloud console. If you have agreed with our sales on a contract and received an email to process the contract online, you can go to the Contract tab to review and accept the contract. To learn more about contracts, feel free to contact our sales.

Documentation changes

  • Add documentation for TiDB Cloud Terraform Provider.

    TiDB Cloud Terraform Provider is a plugin that allows you to use Terraform to manage TiDB Cloud resources, such as clusters, backups, and restores. If you are looking for a simple way to automate resource provisioning and your infrastructure workflow, you can try out TiDB Cloud Terraform Provider according to the documentation.

October 11, 2022

General changes

Console changes

  • Optimize billing information on the billing details page:

    • Provide more fine-grained billing information at the node level in the Summary By Service section.

    Using the new UI, you can preview the data to be imported, view the import process, and manage all import tasks easily.

API changes

  • The TiDB Cloud API (beta) is now available to all users.

    You can start using the API by creating an API key on the TiDB Cloud console. For more information, refer to API documentation.

September 15, 2022

General changes

  • Support connecting to TiDB Cloud Dedicated Tier clusters via TLS.

    For Dedicated Tier clusters, the Standard Connection tab in the Connect dialog now provides a link to download the TiDB cluster CA and also provides the connection string and sample code for TLS connection. You can connect to your Dedicated Tier cluster via TLS using third-party MySQL clients, MyCLI, and multiple connection methods for your applications, such as JDBC, Python, Go, and Node.js. This feature ensures the security of data transmission from your applications to TiDB clusters.

September 14, 2022

Console changes

  • Optimize the UI of the Clusters page and the cluster overview page for better user experience.

    In the new design, the entrances of upgrade to Dedicated Tier, cluster connection, and data import are highlighted.

    • For each 2 vCPU, 8 GiB (Beta) TiKV node, the storage size is between 200 GiB and 500 GiB.

    • Suggested usage scenarios:

      • Low-workload production environments for SMB
      • PoC and staging environments
      • Development environments

      • Development environments

  • Add a Monitoring page to the Diagnosis tab for Dedicated Tier clusters.

    The Monitoring page provides a system-level entry for overall performance diagnosis. According to the top-down performance analysis methodology, the Monitoring page organizes TiDB performance metrics based on database time breakdown and displays these metrics in different colors. By checking these colors, you can identify performance bottlenecks of the entire system at the first glance, which significantly reduces performance diagnosis time and simplifies performance analysis and diagnosis.

  • Add a switch to enable or disable Custom Pattern on the Data Import page for CSV and Parquet source files.

    The Custom Pattern feature is disabled by default. You can enable it when you are going to import CSV or Parquet files whose filenames match a certain pattern to a single target table.

    For more information, see Import CSV Files and Import Apache Parquet Files.

  • Add TiDB Cloud Support Plans (Basic, Standard, Enterprise, and Premium) to meet different support needs of customers' organizations. For more information, see TiDB Cloud Support.

  • Optimize the UI of the Clusters page and the cluster details page:

July 26, 2022

  • Support automatic hibernation and resuming for new Developer Tier clusters.

    A Developer Tier cluster will not be deleted after 7 days of inactivity so you can still use it at any time until the one-year free trial ends. After 24 hours of inactivity, the Developer Tier cluster will hibernate automatically. To resume the cluster, either send a new connection to the cluster or click the Resume button in the TiDB Cloud console. The cluster will be resumed within 50 seconds and back to service automatically.

  • Add a user name prefix limitation for new Developer Tier clusters.

    Whenever you use or set a database user name, you must include the prefix for your cluster in the user name. For more information, see User name prefix.

  • Disable the backup and restore feature for Developer Tier clusters.

    The backup and restore feature (including both automatic backup and manual backup) is disabled for Developer Tier clusters. You can still use Dumpling to export your data as a backup.

  • Increase the storage size of a Developer Tier cluster from 500 MiB to 1 GiB.

  • Add breadcrumbs to the TiDB Cloud console to improve the navigation experience.

  • Support configuring multiple filter rules when you import data into TiDB Cloud.

  • Remove the Traffic Filters page from Project Settings, and remove the Add Rules from Default Set button from the Connect to TiDB dialog.

July 19, 2022

  • Provide a new option for TiKV node size: 8 vCPU, 32 GiB. You can choose either 8 vCPU, 32 GiB or 8 vCPU, 64 GiB for an 8 vCPU TiKV node.

July 05, 2022

  • The columnar storage TiFlash is now in General Availability (GA).

    • TiFlash makes TiDB essentially an Hybrid Transactional/Analytical Processing (HTAP) database. Your application data is first stored in TiKV and then replicated to TiFlash via the Raft consensus algorithm. So it is real time replication from the row storage to the columnar storage.

    • For tables with TiFlash replicas, the TiDB optimizer automatically determines whether to use either TiKV or TiFlash replicas based on the cost estimation.

      To experience the benefits brought by TiFlash, see TiDB Cloud HTAP Quick Start Guide.

  • Support increasing the storage size of TiKV and TiFlash for a Dedicated Tier cluster.

  • Support showing the memory information in the node size field.

  • Support obtaining bucket regions from bucket URLs automatically during data import to save your effort to fill in such information.

June 16, 2022

  • Simplify the cluster creation process.

    • When you create a cluster, TiDB Cloud provides a default cluster name. You can either use the default name or update it.
    • When you create a cluster, you do not need to set the password on the Create a Cluster page.
    • During or after the cluster creation, you can set the root password to access the cluster and also the IP addresses to connect to the cluster in the Security Quick Start dialog box.

June 14, 2022

  • Upgrade TiDB Cloud to TiDB v6.1.0 for Developer Tier.
  • Optimize the entrance of Project Settings. From the TiDB Cloud console, you can choose a target project and go to its settings easily by clicking the Project Settings tab.
