This document describes the pricing details and free tiers of each billable item in TDMQ for CMQ.
Pay-as-You-Go
API call price
TDMQ for CMQ adopts linear pricing for API calls. API call fees = (number of API calls for message sending + number of API calls for message consumption + number of API calls for message acknowledgment) * API call unit price.
The unit price of API call (USD/1,000,000 calls/hour) is as shown below:
Region | Guangzhou, Shanghai, Nanjing, Beijing, Chengdu | Hong Kong (China), Singapore, Seoul, Tokyo, Silicon Valley, Frankfurt, Virginia | Shenzhen Finance, Beijing Finance, Shanghai Finance |
Unit price (USD/1,000,000 calls/hour) | 0.2857 | 0.3714 | 0.4571 |
The maximum message body size is 1 MB, and the number of API calls is calculated at different rates based on the message size:
Message Size | Rate |
N ≤ 2 KB | 1 |
2 KB < N ≤ 4 KB | 2 |
4 KB < N ≤ 16 KB | 4 |
16 KB < N ≤ 100 KB | 16 |
100 KB < N ≤ 1 MB | 64 |
For example, one 10 KB message (publishing or subscribing) request will be charged as four API calls.
Note:
If batch sending/consumption is used, fees will be calculated separately based on the number of messages sent/consumed in batches. For example, if ten messages are batch sent and each is 2 KB in size, then they will be calculated as 10 * 2 = 20 API calls.
Message storage price
TDMQ for CMQ adopts linear billing for the maximum message storage capacity you set after enabling the message rewind feature. Message storage fees = storage capacity set for message rewind * message storage unit price.
The unit price of message storage (USD/GB/hour) is as shown below:
Region | Guangzhou, Shanghai, Nanjing, Beijing, Chengdu | Hong Kong (China), Singapore, Seoul, Tokyo, Silicon Valley, Frankfurt, Virginia | Shenzhen Finance, Beijing Finance, Shanghai Finance |
Unit price (USD/GB/hour) | 0.0004 | 0.0004 | 0.0007 |
The number of message replicas is 3 by default and cannot be adjusted currently.
For example, messages of queue A created in Guangzhou region are very important to the business, so message rewind is enabled, and a message rewind space of 10 GB is set. Then, the fees incurred on the next day will be calculated as follows: 0.0004 x 3 x 10 x 24 = USD 0.288.
Note:
No message storage fees will be incurred if you don't enable message rewind for the queue.
No matter how much storage capacity is actually used, fees will be always charged based on the set maximum storage capacity.
