When calculating the amount, the banker billing mode is adopted, retaining 2 decimal places and rounding off. If the last digit is 5 and its previous digit is odd, it will be rounded up; if the previous digit is even, it will be rounded down. You can quickly get prices through the TSDB Price Calculator.

TSDB provides instant database services with data writing, storage, query and other capabilities in the form of APIs. Users do not need to purchase virtual machine instances but only needs to purchase the monthly write and query limits.

A proper estimation should be made on the number of written data points and query capabilities per month prior to the purchase. A small number of configurations, such as business growth, is recommended to purchase, and Automatic Upgrade can be performed later via the console.

Note: When the user purchase service of 10, 11, or 12 months, due to the preferential policy, 10-month-service is actually paid while the 1-year service is provided.

The first 100,000 query units of each database are free of charge. 3. The operation of the Console is billed based on the same rule. 4. Please refer to the bottom of this page for the interface generating query fees.	Not necessary

Note ：

• The original configuration of "free data storage for 5 years" cannot be newly purchased, but can be renewed and upgraded normally. If you want to upgrade the original "free data storage 5 years" database to "data free storage for 1 year" database, the total number of points already stored in the original database will be charged for renewal fee for one year after the upgrading configuration takes effect. Please submit a Ticket to apply for. If monthly write quota is less than 100 million points, no upgrade service will be provided.

Purchase Guide

Scenario:

You need to monitor data of 1,000 devices, each with 10 monitoring points, and each monitoring point reports data every minute. Data of one monitoring point requires to be stored in string type at a length of 100B. You make 100 queries per day in the console, each query covers 1,000 data points, the number of queries that the business system calls query interface API is 100 queries per minute, and each query covers 1,000 data points.

Usage:

• The number of data points to be reported each month is 60*24*30*10*1000 = 4320000
• The number of time series is 10*1000 = 10000
• The number of queries is 100*30+100*60*24*30 = 4330000
• Storage space for long data format is 100B*60*24*30*1000 = 4.32 GB

Purchase:

• Write limit is 432 million/month with RMB 598.4
• Query limit is 4.33 million/month with RMB 1.692
• Storage space for long data format is 4.32 GB/month with RMB 2.5

Monthly fee paid is:

• 598.4 + 16.92 + 2.5 = 617.82 (CNY)

Billing Query Interface

Interface	Method	API	Instruction
Query data point	GET	/v1/datapoint?query={json}	Query data point and query a parameter in query parameters, including console calls
Query data point	PUT	/v1/datapoint?query	Query data point and query a parameter in body, including console calls
SQL query data point	GET	/v1/row?sql={statement}	Query time series data by using ANSI SQL, including console calls and API/SDK calls
Preprocessing	Console Call	Console Call	Data points processed based on preprocessing rules

For detailed interface, see API Documentation For system limitation, see Documentation

Note:

1.Scanned counts of data points (consumedCount) are billed, and the value of ceiling consumedCount/1000 is the query unit of this query;

2.If there is a limit parameter, the return points for each time series is limited to limit. The scanned counts of data points (consumedCount) by the system are related to both the limit parameter and the number of time series, and the scanned counts (consumedCount) can be reduced by reducing the number of time series and setting the limit parameter

3.Query fee is not required if there is an internal error of the system

4.Time-out queries are also counted as query units. Properly construct query statements to prevent timeouts. The return time below is used as a reference, but not as an SLA guarantee.

If the query request is within 100 time series,

a) return time is between 200ms to 300ms for 10,000 scanned counts of data points

b) return time is between 2000ms to 3000ms for 100,000 scanned counts of data points

c) return time is within 20s for 1,000,000 scanned counts of data points

Upgrade Configuration

Users who have business growth requirements may follow the following operating steps to upgrade, and the Billing Mode of the upgrade fee is the same as that of the prepaid fee:

1. Select Product Service > Time Series Database TSDB > Product Name, and enter the database details page.
2. Click Basic Information > Configuration Information > Upgrade Configuration, to upgrade and configure the console.
