Understanding Billing for Database Replication

Charges based on database replication are divided into two categories: data transfer and compute resources. Both categories are billed on the target account (i.e. the account that stores the secondary database that is refreshed).

Data transfer

The initial database replication and subsequent synchronization operations transfer data between regions. Cloud providers charge for data transferred from one region to another within their own network.

The data transfer rate is determined by the location of the source account (i.e. the account that stores the primary database). For data transfer pricing, see the pricing page (on the Snowflake website).

For more information about data transfer billing, see Understanding Snowflake Data Transfer Billing.

Compute resources

Replication operations use Snowflake-provided compute resources to copy data between accounts across regions.

Note

  • The target account also incurs standard storage costs for the data in each secondary database in the account.

  • If the initial database replication or a subsequent refresh operation fails, the next attempt (if performed within 14 days) can reuse the data that was already copied; that is, the data is not copied again during the next attempt. For this reason, database replication charges are applied even if the initial database replication or a subsequent refresh operation fails.

Estimating and Controlling Costs

In general, monthly billing for database replication is proportional to:

  • Amount of table data in the primary database that changes as a result of data loading or DML operations.

  • Frequency of secondary database refreshes from primary databases.

You can control the cost of replication by carefully choosing which primary databases to replicate and their refresh frequency. You can stop incurring replication costs by ceasing database refresh operations.

Viewing Actual Costs

Users with the ACCOUNTADMIN role can use the Snowflake web interface or SQL to view the amount of replication data transferred (in bytes) for your Snowflake account within a specified date range.

To view the data transfer amounts for your account:

Web Interface

Click on Account Account tab » Billing & Usage. Replication utilization is shown as a special Snowflake-provided warehouse named Snowflake logo in blue (no text) REPLICATION. Click the Data Transfer button to view the data transfer costs. Note that the web interface does not break down data transfer costs for replication.

SQL
