Yandex Data Streams pricing policy
To calculate the cost of using the service, see the prices in this section.
Data Streams supports two pricing modes:
- Based on allocated resources: You pay a fixed hourly rate for the established throughput limit and message retention period and additionally for the number of units of actually written data.
- On-demand: You pay for data writes and reads performed, the amount of data read/written, and the size of storage actually used for messages with a valid retention period.
The pricing mode is set for each data stream individually. By default, streams in Data Streams are created with pricing based on allocated resources.
Pricing based on allocated resources
If pricing for allocated resources is used, the number of units of written data and resources allocated for streaming data are billed.
Pricing for the allocated resources includes the established segment throughput limit as well as storage time and size.
You get the first 744 hours of data storage and data stream maintenance with the following characteristics at no charge every month:
- Segment write speed: no more than 128 KBps.
- Message retention period: 1 hour.
- Number of data units written per month: no more than 2 million.
After you've used up your free service amounts, you will be charged at the applicable rate. The unused balance of free services is reset at the end of the month.
Examples of cost calculation
A single-shard stream receives two 50 KB messages per second. The message retention period is 12 hours.
Data processing cost per month (for a 31-day month):
(50 / 40) = 2
Where:
- 50: Size of one message in KB.
- 40: Size of units of written data in KB.
- 2: Number of data units written per message.
While calculating the cost, the number of units of written data is rounded up to an integer. In this example, the number is rounded to 2.
2 × 2 = 4
Where:
- 2: Number of messages per second.
- 2: Number of data units written per message.
- 4: Number of data units written per second.
4 × 60 × 60 × 24 × 31 = 10,713,600
Where:
- 4: Number of data units written per second.
- 60 × 60 × 24 × 31: Number of seconds in the month.
- 10,713,600: Number of data units written per month.
₽0.1333 × 24 × 31 = ₽99.1752
Where:
- ₽0.1333: Cost of allocated resources per hour when stored for 12 hours.
- 24: Number of data storage hours.
- 31: Number of days in a month.
- ₽99.1752: Cost of allocated resources per month with a maximum data write speed of 128 KB/s and a storage period of 24 hours, including VAT.
(10,713,600 - 2,000,000) / 1,000,000 × ₽1.18 + ₽99.1752 = ₽109.4572
Where:
- 10,713,600: Number of data units written per month.
- 2,000,000: Number of free units per month.
- ₽1.18: Cost of 1 million units of written data, including VAT.
- ₽99.1752: Cost of allocated resources per month with a maximum data write speed of 128 KB/s and a storage period of 24 hours, including VAT.
Total: ₽109.4572, including VAT.
(50 / 40) = 2
Where:

- 4: Number of data units written per second.
- 60 × 60 × 24 × 31: Number of seconds in the month.
- 10,713,600: Number of data units written per month.
₸0.80 × 24 × 31 = ₸595.20

- 31: Number of days in a month.
- ₸595.20: Cost of allocated resources per month with a maximum data write speed of 128 KB/s and a storage period of 24 hours, including VAT.
(10,713,600 - 2,000,000) / 1,000,000 × ₸7.08 + ₸595.20 = ₸656.8923
