An instance is the basic unit of resource management in Tablestore. Access control and resource metering for applications in Tablestore are performed at the instance level. This topic describes how to create an instance.
Usage notes
Each Alibaba Cloud account can create up to 10 instances. The name of an instance must be unique within the region in which the instance resides. To increase the quota, submit a ticket.
After you create an instance, you cannot modify the region or type of the instance. Proceed with caution.
NoteThe features supported by Tablestore vary based on regions. For more information, see Features and regions.
Prerequisites
Tablestore is activated. For more information, see Activate Tablestore.
Procedure
You can perform the following operations in the Tablestore console to create an instance or an instance for the TimeSeries model.
Create an instance
Log on to the Tablestore console.
In the top navigation bar, select a resource group and a region.
The instance types that the region supports are displayed in the console.
Click Create Instance.
On the CU Mode (Formerly On-demand Mode) tab of the Billing Method dialog box, configure the parameters for the instance. The following table describes the parameters.
Parameter
Description
Region
The region in which you want to create the instance.
Resource Group
The resource group to which the instance belongs.
Instance Name
The name of the instance. The name must meet the following requirements:
The name can contain only letters, digits, and hyphens (-).
The name must start with a letter.
The name cannot end with a hyphen (-).
The name is not case-sensitive.
The name must be 3 to 16 characters in length.
The name cannot contain the following words:
ali,ay,ots,taobao, oradmin.
Instance Type
The type of the instance. Select a suitable instance type based on your business requirements. For information about how to select a suitable instance type, see Instance types.
High-performance: suitable for online scenarios in which high concurrency and extremely low read and write latency are required.
Capacity: suitable for offline scenarios in which lower-cost data storage is required. This type is not suitable for online scenarios that are sensitive to access latency.
Redundancy Type
Tablestore supports locally redundant storage (LRS) and zone-redundant storage (ZRS).
If your business requires higher availability, we recommend that you create an instance in a region that supports ZRS. For more information, see ZRS.
Instance Description
The description of the instance, such as the purpose of the instance.
Tag
You can bind tags to instances to classify and manage the instances. For more information, see Use tags to manage instances.
If you want to modify the network type or source that is allowed to access the instance, turn on the Advanced Settings option and configure the parameters. The following table describes the parameters.
Parameter
Description

Create an instance for the TimeSeries model
The following regions support the TimeSeries model: China (Hangzhou), China (Shanghai), China (Beijing), China (Zhangjiakou), China (Ulanqab), China (Shenzhen), China (Chengdu), China (Hong Kong), Japan (Tokyo), Singapore, Malaysia (Kuala Lumpur), Indonesia (Jakarta), Germany (Frankfurt), UK (London), US (Silicon Valley), and US (Virginia). If the Create Instance for TimeSeries Model button is not available in the preceding regions, you can click Create Instance to create an instance for the TimeSeries model.
The following regions support the Lastpoint index and Analytical store for time series features: China (Hangzhou), China (Shanghai), China (Beijing), and China (Zhangjiakou). If you want to use these features, create an instance for the TimeSeries model in one of these regions.
Log on to the Tablestore console.
In the top navigation bar, select a resource group and a region.
On the Overview page, click Create Instance for TimeSeries Model.
In the Create Instance for TimeSeries Model dialog box, configure the parameters for the instance. The following table describes the parameters.
Parameter
Description
Region
The region in which you want to create the instance.
Analytical Store
An analytical store is a low-cost storage engine designed by Tablestore for time series scenarios. It not only supports efficient data compression and storage but also provides powerful query and analysis capabilities, which is suitable for large-scale data analysis and query tasks.
We recommend that you create an instance in a region that supports the analytical store feature.
Instance Type
Select a suitable instance type based on your business requirements. For information about how to select a suitable instance type, see Instance types.
High-performance: suitable for online scenarios in which high concurrency and extremely low read and write latency are required.
