Server

Optimized resources processing

This release includes major improvements that allow the dstack server process more resources quickly. It also allows scaling processing rates of one server replica to take advantage of big Postgres instances by setting the DSTACK_SERVER_BACKGROUND_PROCESSING_FACTOR environment variable.

The result is:

  • Faster processing rates: provisioning 100 runs on SQLite with default settings went from ~5m to ~2m.
  • Better scaling: provisioning additional 100 runs is even quicker due to warm cache. Before, it was slower than the first 100 runs.
  • Ability to process more runs per server replica: provisioning 300 runs on Postgres with DSTACK_SERVER_BACKGROUND_PROCESSING_FACTOR=4 is ~4m.

For more details on scaling backgraound processing rates, see the Server deployment guide.

Backends

Private GCP gateways

It's now possible to create GCP gateways without public IPs:

:::yaml
type: gateway
name: example
domain: gateway.example.com
backend: gcp
region: europe-west9
public_ip: false
certificate: null

Note that configuring HTTPS certificates for private GCP gateways is not yet supported, so you need to specify certificate: null.
