What goes into the cost of using Data Streams

While using Data Streams, the number of units of written data and resources allocated for streaming data are billed.

Pricing for allocated resources is based on the limit of the shard throughput and data retention period.

A single-shard stream receives two 50 KB messages per second. The message retention period is 12 hours.

Calculation of the monthly cost of processing data (provided that there are 31 days in the month):

⌈ 50 / 40 ⌉ = 2

Where:

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:

4 × 60 × 60 × 24 × 31 = 10 713 600

Where:

10 713 600 / 1 000 000 × 0.015128 + 1.230769 =
