Billing rules of Tablestore - Tablestore - Alibaba Cloud Documentation Center

You are charged for resources of each Tablestore instance. This topic describes the pricing, billing method, and billable items of Tablestore.

Pricing

For information about the pricing of Tablestore, see the Pricing tab of the Tablestore product page.

Billing method

You are charged based on the pay-as-you-go billing method when you use Tablestore resources. This billing method indicates that you are charged for the Tablestore resources that you used on an hourly basis.

Important

When the pay-as-you-go billing method is used, the system cannot control the upper limit of the overall resource usage. You must manage the resource usage based on your business requirements to avoid Tablestore resource overheads caused by unexpected traffic and resource usage.

Billable items

The following table describes the billable items of Tablestore.

Billable item		Description
Storage usage		The average of total data size in each hour of a billing cycle.
Read throughput	Reserved read throughput	The average of reserved read throughput that is consumed by your account in each hour of a billing cycle. Note Only high-performance instances support reserved read throughput. For more information about instances, see Instance.
	Metered read throughput	The metered read throughput per second. You are charged for the sum of the metered read throughput that is consumed by your account in a billing cycle.
Write throughput	Reserved write throughput	The average of reserved write throughput that is consumed by your account in each hour of a billing cycle. Note Only high-performance instances support reserved write throughput. For more information about instances, see Instances.
	Metered write throughput	The metered write throughput per second. You are charged for the sum of the metered write throughput that is consumed by your account in a billing cycle.
Outbound traffic over the Internet		The total Internet outbound traffic that is generated when applications access Tablestore by using HTTP methods. Note You are not charged for traffic over the internal network and inbound traffic. If access to Tablestore fails, Tablestore returns access failure information, which also generates outbound traffic. If your client sends a request to access Tablestore resources that are located in a region different from your client, the connection is established over the Internet.

Search index	You are charged for high-performance storage usage, reserved read throughput, and metered read throughput when you use the search index feature regardless of the instance type. For more information, see Billable items of search indexes.
SQL query	Computing in SQL statements does not consume read and write throughput. However, when you execute SQL statements to query data, operations such as data table scanning and index-based queries consume read and write throughput. For more information, see Billable items of SQL query.
Secondary index	The billable items include the storage usage, read and write throughput that is consumed when you create a secondary index, and read and write throughput that is consumed when you perform read and write operations on the secondary index. For more information, see Billable items of secondary indexes.
TimeSeries model	The billable items include the storage usage and the metered read and write throughput. For more information, see Billable items of the TimeSeries model.
Max versions	You are charged for the storage usage of version numbers and data with various version numbers. For more information, see Storage usage.
