Datastream pricing
Overview
This page describes pricing for Datastream. To see the pricing for other products, read the Pricing documentation.
If you pay in a currency other than USD, then the prices listed in your currency on Google Cloud SKUs apply.
Pricing summary
Datastream pricing is based on gigabytes (GBs) processed. Usage is billed in per-byte increments, on a per-stream basis, and is stated in GB (500 MB is 0.5 GB, for example). Bytes are counted, based on raw (uncompressed) data.
Change data capture (CDC) and backfill
Datastream streams data from a source to a destination by one of two methods:
- Change data capture (CDC): Datastream captures ongoing changes from the source in real time.
- Backfill: Datastream takes a historical snapshot of data that exists in a table.
Each streaming method is charged at a different rate, described in Pricing details.
Pricing details
In this section, you'll see the charges that apply for each streaming method when using Datastream.
To see the costs that you'll incur for using Datastream for a region where Datastream is available, select a region from the drop-down menu below.
Datastream CDC costs are tiered, meaning that as your usage increases, the price per GB decreases. The reduced price applies only to usage within the tier (GBs processed in lower tiers will still be charged based on the cost for that tier). Backfill uses a flat rate, but the first 500 GB each month is free. See a detailed example below.
Contact sales for pricing beyond 10 TB (CDC).
Usage of other Google Cloud resources
In addition to the cost of data processed by Datastream, you're billed for any resources that you use to transfer, store, or process your data, such as:
Pricing example
As an example, consider a stream that processes data from a source with the following characteristics:
| Backfill of data currently in the source | 600 GB |
| Volume of changes in a month (CDC) | 3,000 GB |
| Destination | Cloud Storage |
| Region | Iowa (us-central1) |
This Datastream stream will perform a one-time backfill of existing data, as well as capture changes from the source. Data is stored in files on Cloud Storage in the same region where Datastream is configured.
Datastream pricing would use the following formula:
Backfill charge = (backfill size - 500 GB) * backfill price = (600 - 500) * $0.40 = $40.00
CDC charge = (2,500 GB * $2.00/GB) + (500 GB * $1.50/GB) = $5,000.00 + $750.00 = $5,750.00
Total Datastream charge = Backfill charge + CDC charge = $40.00 + $5,750.00 = $5,790.00
In this example, additional charges would be incurred for the source and for data stored in Cloud Storage. The Pricing calculator can be used to estimate separate Google Cloud resource costs.
