Data transfer

Understand how ClickHouse Cloud meters data transferred ingress and egress

ClickHouse Cloud meters data transferred ingress and egress. This includes any data in and out of ClickHouse Cloud as well as any intra-region and cross-region data transfer. This usage is tracked at the service level. Based on this usage, customers incur data transfer charges that are then added to their monthly bill.

ClickHouse Cloud charges for:

• Data egress from ClickHouse Cloud to the public Internet, including to other regions of other cloud providers.
• Data egress to another region in the same cloud provider.

There are no charges for intra-region data transfer or Private Link/Private Service Connect use and data transfer. However, we reserve the right to implement additional data transfer pricing dimensions if we see usage patterns that impact our ability to charge users appropriately.

Note: Cloud Service Provider (CSP) charges apply for Private Link/Private Service Connect usage. Please refer to the CSP’s pricing page for the most up-to-date information.

Data transfer charges vary by Cloud Service Provider (CSP) and region. Public internet egress pricing is based only on the origin region. Inter-region (or cross-region) pricing depends on both the origin and destination regions.

Best Practices to minimize Data Transfer Costs

There are some patterns to keep in mind when ingressing and egressing data to minimize data transfer costs.

1. When ingressing or egressing data from Clickhouse Cloud, use compression where possible, to minimize the amount of data transferred and the associated cost.

2. Be aware that when doing an INSERT over the native protocol with non-inlined values (e.g. INSERT INTO [TABLE] FROM INFILE [FILE] FORMAT NATIVE), ClickHouse clients pull metadata from servers to pack the data. If the metadata is larger than the INSERT payload, you might counterintuitively see more egress than there is ingress from the server perspective. If this is unacceptable, consider inlining data with VALUES syntax or using the HTTP protocol.

The tables below shows how data transfer charges for egress vary across public internet or cross-region by cloud provider and region.

ClickHouse Cloud meters inter-region usage in terms of tiers, Tier 1 through Tier 4, depending on the origin and destination regions. The table below shows the tier for each combination of inter-region data transfer. In the Billing usage screen on ClickHouse Cloud you will see data transfer usage broken out by tiers.

The table below shows how data transfer charges for egress vary across public internet or cross-region by cloud provider and region.
