What is TiDB Serverless?
TiDB Cloud Serverless Tier provides you and your organization with a TiDB database that has full HTAP capabilities. It is a fully managed, auto-scaling deployment of TiDB that allows you to start using the database immediately, develop and run applications without worrying about the underlying nodes, and automatically scale according to the workload changes of the application.
How to get started with TiDB Serverless?
Get started with the 5-minute TiDB Cloud Quick Start.
Is TiDB Serverless free during the testing period?
Yes. TiDB Serverless is free to use during the testing phase. In the coming months, we plan to offer usage-based billing plans for more resources and higher performance, while continuing to provide a free starter plan.
What does this mean for the beta version?
The Serverless Tier is in the testing phase, and we will continuously add new features and improve existing ones before their official release. We do not provide an SLA for beta products. Therefore, TiDB Serverless should not be used in production at this time.
What are the limitations of TiDB Serverless clusters in the free beta version?
-
For each TiDB Cloud account, you can create one free TiDB Serverless cluster during the testing phase. To create a new TiDB Serverless cluster, you need to delete the existing cluster first.
-
Each TiDB Serverless cluster has the following limitations:
-
The storage size for OLTP storage is limited to 5 GiB (logical size) and 5 GiB for OLAP storage.
-
Compute resources are limited to 1 vCPU and 1 GiB of memory.
-
Note: In the coming months, we plan to offer usage-based billing plans for more resources and higher performance, while continuing to provide a free starter package. The limitations of the free TiDB Serverless may change in upcoming releases.
-
-
TiDB Serverless partially supports or does not support certain features of TiDB Cloud. For more details, refer to TiDB Serverless Limitations.
What can TiDB Serverless be used for?
- You can use the Serverless Tier cluster for non-production workloads such as prototype applications, development environments, hackathons, and academic courses, or to provide temporary data services for datasets.
I created a Developer Tier cluster before TiDB Serverless was available. Can I still use my cluster?
Yes, your free Developer Tier cluster will soon be automatically migrated to a TiDB Serverless cluster. Your ability to use the cluster should not be affected, and you will get the same TiDB Serverless user experience.
Is my TiDB Serverless shared or dedicated?
TiDB Serverless technology is designed for multi-tenant technology, and all clusters use shared resources. To get a managed TiDB service with isolated infrastructure and resources, you can upgrade to the Dedicated Tier.
How does TiDB Serverless ensure security?
-
Your connection is encrypted by Transport Layer Security (TLS). For more information on connecting to TiDB Serverless using TLS, refer to Secure Connections to Serverless Tier Clusters.
-
All persistent data on the Serverless Tier is encrypted at rest using tools from the cloud provider running the cluster.
Can I upgrade the TiDB version my cluster is running?
No. When we release new TiDB versions on TiDB Cloud, TiDB Serverless clusters are automatically upgraded. You can check the TiDB version your cluster is running in the TiDB Cloud Console or the latest release notes. Alternatively, you can connect to your cluster and use SELECT version() or SELECT tidb_version() to check the TiDB version.
