Frontend Groups

Private preview

The Frontend Groups page lets you view and scale the FE (Frontend) resource group of your warehouse. FE nodes handle query parsing, planning, and metadata management. VeloDB Cloud provides a free FE baseline for every warehouse; you can expand to a larger specification when your workload demands it.

Frontend Groups is currently available in Private Preview. To enable it for your organization, contact the VeloDB support team.

FE resource specifications

Each warehouse is provisioned with a default Small FE group at no charge. You can scale up to larger specifications when needed. Scaling up is charged per vCPU at the Cluster Compute rate.

Specification	Compute	Pricing
Small	4 vCPU, 16 GB RAM	Free
Medium	8 vCPU, 32 GB RAM	Billed by vCPU-Hour
Large	16 vCPU, 64 GB RAM	Billed by vCPU-Hour
XLarge	32 vCPU, 128 GB RAM	Billed by vCPU-Hour

The free Small specification covers the vast majority of use cases. Expansion is typically needed only when the warehouse has an extremely high number of data shards or extremely high concurrent query volume.

Prerequisites

The Frontend Groups feature is available to warehouses that have been enabled for FE group expansion. Contact VeloDB support to enable this feature for your warehouse.

Once enabled, Frontend Groups appears in the warehouse navigation menu, under the Compute section.

View the default Frontend Group

In the left navigation pane, under the Compute section, click Frontend Groups to open the list page. Each warehouse has one default FE group named meta. The card displays the current compute specification, node count, and creation time.

Click the meta card to open the Frontend Group detail page.

The detail page shows:

• Frontend Group ID: unique identifier of the FE group.
• Frontend Group Name: editable display name.
• CPU Architecture: the architecture of the underlying nodes.
• Created At / Started At / Running Time: lifecycle timestamps.
• On-Demand Resources: current compute specification and node count.

Scale the Frontend Group

If your warehouse experiences FE bottlenecks (slow query planning, high concurrency latency, or metadata slowdowns), you can scale the FE group to a larger specification.

1. On the Frontend Group detail page, click Scale Out/In.

2. In the Scaling Configuration panel, review the Current Configuration and select a Target Configuration under Compute.

3. Under Target Configuration, select a compute size.

4. Confirm the On-Demand New Cost shown at the bottom of the panel, then click Confirm.

Billing switches to the new specification immediately after scaling completes.

Billing

After scaling above the free Small specification, a new Fe Compute billing item appears in Billing → Billing Statements.

The Billing Statements page displays a table with the following information for each billing item:

Column	Description
Start Time / End Time	The billing period in UTC.
Component	The billed resource (e.g., Fe Compute, Cluster Compute, Cluster Cache, Storage).
Billing Method	The billing method (e.g., On-Demand).
Usage	The measured usage (e.g., vCPU-Hour, GB-Hour).

You can filter by Monthly, Daily, or Hourly granularity, select a date range, and click Export to download the statement.

If you scale back down to Small, the Fe Compute billing item is removed and the FE group returns to the free tier.
