Data transfer

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.

Managed Postgres

ClickHouse Managed Postgres public-internet and cross-region data egress are billed at the rates described on this page. Data transfer is classified by destination IP against the cloud provider’s published IP ranges. Traffic to a destination whose IP is not in your region’s published ranges is metered as public-internet egress, even when that destination is hosted on the same cloud provider — for example, a peer that uses its own IP block (BYOIP). If you connect to such a peer, contact support so we can review the classification. ClickPipes compute is free when used to replicate data from Managed Postgres to ClickHouse Cloud. Egress from Managed Postgres to ClickPipes is metered like any other data transfer: no charge when both are in the same region; cross-region replication is billed at the applicable inter-region tier, and replication to a ClickHouse Cloud service on a different cloud provider at the public-internet rate. To reduce data transfer costs, co-locate your application and Managed Postgres in the same region of the same cloud provider whenever possible. 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.
