TiDB Cloud Release Notes in 2022

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

December 28, 2022

General changes

  • Currently, after upgrading the default TiDB version of all Serverless Tier clusters from v6.3.0 to v6.4.0, the cold start becomes slower in certain circumstances. So we roll back the default TiDB version of all Serverless Tier clusters from v6.4.0 to v6.3.0, then fix the problem as soon as possible, and upgrade it later again.

December 27, 2022

General changes

  • Upgrade the default TiDB version of all Serverless Tier clusters from v6.3.0 to v6.4.0.

  • The point-in-time recovery (PITR) for Dedicated Tier clusters is now in General Availability (GA).

    PITR supports restoring data of any point in time to a new cluster. To use the PITR feature, make sure that your TiDB cluster version is at least v6.4.0 and the TiKV node size is at least 8 vCPU and 16 GiB.

    You can enable or disable the PITR feature in the Backup Settings of the TiDB Cloud console.

    For more information, see Back up and restore TiDB cluster data.

  • Support managing multiple changefeeds and editing existing changefeeds.

    • You can now create as many changefeeds as needed to manage different data replication tasks. Currently, each cluster can have up to 10 changefeeds. For more details, refer to Changefeed overview.
    • You can edit the configuration of an existing changefeed in the paused status. For more information, see Edit a changefeed.

  • Support directly migrating data from Amazon Aurora MySQL, Amazon Relational Database Service (RDS) MySQL, or self-hosted MySQL-compatible databases to TiDB Cloud online. This feature is now in General Availability.

    • Provide services in the following 6 regions:
      • AWS Oregon (us-west-2)
      • AWS N. Virginia (us-east-1)
      • AWS Mumbai (ap-south-1)
      • AWS Singapore (ap-southeast-1)
      • AWS Tokyo (ap-northeast-1)
      • AWS Frankfurt (eu-central-1)
    • Support multiple specifications. You can choose an appropriate specification according to the required performance to achieve optimal data migration experience.

    For how to migrate data to TiDB Cloud, refer to user documentation. For billing details, refer to Data Migration billing.

  • Support importing local CSV files to TiDB Cloud.

    It only takes a few clicks to complete the task configuration, and then your local CSV data can be quickly imported into your TiDB cluster. When using this method, you do not need to provide the cloud storage bucket path and Role ARN. The whole importing process is quick and smooth.

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

December 20, 2022

General changes

  • Add the label project name to the Datadog Dashboard as a filter to provide project information.

    You can use the filter project name to quickly find the cluster you want.

December 13, 2022

General changes

  • Introduce TiDB Cloud SQL Editor (Beta) for Serverless Tier.

    This is a web-based SQL editor that allows you to directly edit and run SQL queries against databases of Serverless Tier. You can locate it easily in the left navigation bar of your Serverless Tier cluster.

    For Serverless Tier, the Web SQL Shell is replaced by the SQL Editor.

  • Support using Changefeeds to stream data for Dedicated Tier.

    • Support streaming data change logs to MySQL.

      When data is migrated from MySQL/Aurora to TiDB, it is often necessary to use MySQL as a stand-by database to prevent unexpected data migration problems. In this case, you can use MySQL sink to stream data from TiDB to MySQL.

    • Support streaming data change logs to Apache Kafka (Beta).

      Streaming TiDB data to the message queue is a very common requirement for data integration scenarios. You can use Kafka sink to realize integration with other data processing systems (such as Snowflake), or support business consuming.

      For more information, refer to Changefeed Overview.

  • Organization owners can edit the organization's name in Organization Settings.

Console changes

  • Optimize the navigation layout of the TiDB Cloud console to provide users with a new navigation experience.

    The new layout includes the following changes:

    • Introduce the left navigation bar to maximize screen usage efficiency.
    • Adopt a flatter navigation hierarchy.

  • Improve the Connect experience for Serverless Tier users.

    Now developers can connect to SQL editor or with their preferred tools in just a few clicks without context switching.

December 6, 2022

General changes

November 29, 2022

General changes

  • Improve the user experience from AWS Marketplace and Google Cloud Marketplace.

    No matter whether you are new to TiDB Cloud or you already have a TiDB Cloud account, now you can link with your AWS or GCP billing account, which makes it easier to complete AWS or GCP Marketplace subscriptions.

    For how to make the link, see Billing from AWS Marketplace or Google Cloud Marketplace.

November 22, 2022

General changes

  • Support directly migrating data from Amazon Aurora MySQL, Amazon Relational Database Service (RDS) MySQL, or self-hosted MySQL-compatible databases to TiDB Cloud online (beta).

    Previously, you needed to pause your business and import data offline, or use third-party tools to migrate data to TiDB Cloud, which was complicated. Now, with the Data Migration feature, you only need to perform operations on your TiDB Cloud console and securely migrate your data to TiDB Cloud with minimal downtime.

    In addition, Data Migration provides full and incremental data migration capabilities to migrate both existing data and ongoing changes from your data source to TiDB Cloud.

    Currently, the Data Migration feature is still in beta. It is available only for Dedicated Tier clusters and only in the AWS Oregon (us-west-2) and AWS Singapore (ap-southeast-1) regions. You can create one migration job for free for each organization. To create multiple migration jobs for an organization, you need to file a ticket.

    For detailed information, see Migrate MySQL-Compatible Databases to TiDB Cloud Using Data Migration.

November 15, 2022

General changes

  • Support point-in-time recovery (PITR) for Dedicated Tier clusters (beta).

    PITR supports restoring data of any point in time to a new cluster. You can use it to:

    • Reduce RPO in disaster recovery.
    • Resolve data write errors by restoring point-in-time that is before the error event.
    • Audit the historical data of the business.

    To use the PITR feature, make sure that your TiDB cluster version is at least v6.3.0 and the TiKV node size is at least 8 vCPU and 16 GiB.

    By default, backup data is stored in the same region where the cluster is created. In Japan, for TiDB clusters hosted on GCP with PITR enabled, you can choose to store backup data in one or two regions (Tokyo and/or Osaka). Restoring data from an alternative region provides a higher level of data safety and can tolerate region failures.

    For more information, see Back Up and Restore TiDB Cluster Data.

    This feature is still in beta and only available upon request:

    • Click Help in the lower-right corner of TiDB Cloud console.
    • In the dialog, fill in "Apply for PITR" in the Description field and click Send.

  • The database audit logging feature is now GA.

    You can use database audit logging to record a history of user access details (such as any SQL statements executed) in logs and conduct a periodic analysis of the database audit logs, which helps keep your database secure.

    For more information, see Database Audit Logging.

November 8, 2022

General changes

  • Improve the user feedback channel.

    Now you can request a demo or credits in Support > Give Feedback in the TiDB Cloud console. This can be helpful if you want to learn more about TiDB Cloud.

    After receiving your request, we will contact you to provide help as soon as possible.

October 28, 2022

General changes

  • Developer Tier is upgraded to Serverless Tier. Serverless Tier, a fully-managed, auto-scaling deployment of TiDB, is now available. It is still in beta and free to use.

    • A Serverless Tier cluster still contains fully functional HTAP ability as Dedicated Tier clusters.
    • Serverless Tier offers you faster cluster creation time and instantaneous cold start time. Compared with Developer Tier, the creation time reduces from minutes to seconds.
    • You do not need to worry about deployment topology. Serverless Tier will adjust automatically according to your requests.
    • Serverless Tier enforces TLS connection to clusters for the sake of security.
    • Existing Developer Tier clusters will be automatically migrated to Serverless Tier in the coming months. Your ability to use your cluster should not be affected, and you will not be charged for the use of your Serverless Tier cluster in beta.

    Get started here.

October 25, 2022

General changes

  • Support dynamically changing and persisting a subset of TiDB system variables (beta).

    You can use the standard SQL statement to set a new value for a supported system variable.

    SET [GLOBAL|SESSION] <variable>

    For example:

    SET GLOBAL tidb_committer_concurrency = 127;

    If a variable is set at the GLOBAL level, the variable will be applied to the cluster and persistent (keep effective even after you restart or reload the server). A variable at the SESSION level is not persistent and is only effective in the current session.

    This feature is still in beta, and only a limited number of variables are supported. It is not recommended to modify other system variables due to uncertainty of the side effects. See the following list for all supported variables based on TiDB v6.1:

  • Upgrade the default TiDB version of new Dedicated Tier clusters from v6.1.1 to v6.1.2.

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.
