Passthrough mode

Passthrough pauses Yuki's optimization across your whole account. Your connection strings, integrations, and warehouse settings stay exactly as they are - Yuki keeps accepting every query, but passes each one straight through to the warehouse it was originally addressed to without optimizing it.

Where to find it​

Go to Settings > Passthrough. The page shows whether optimization is currently active, along with the number of integrations and warehouses that are covered.

Click Pause optimization to turn Passthrough on. Click the same control again (it now reads Resume optimization) to turn it back off.

note

Pausing optimization is account-wide - it isn't scoped to a single warehouse or integration. To turn optimization off for specific warehouses only, see What it doesn't do below.

When to use it​

Passthrough is an account-wide kill switch, not a tuning option - reach for it when you need to rule Yuki in or out of an issue, not when you want to change how a specific workload is optimized:

  • Isolating a performance problem. If a query or workload is slower or behaving unexpectedly and you're not sure whether Yuki's optimization is the cause, pause optimization and reproduce it.
  • A production incident where you need certainty fast. If you can't afford to spend time diagnosing whether Yuki is contributing to an outage or severe slowdown, Passthrough removes Yuki from the equation immediately while you investigate, without touching connection strings or warehouse configuration.

What it doesn't do​

  • It doesn't disconnect the Yuki Proxy or change any connection string - queries still flow through Yuki, they're just no longer optimized.
  • It doesn't pause cost or usage visibility - the Cost & Savings and other dashboards keep recording data while Passthrough is on, though you won't accrue new savings during that window.
  • It isn't a per-workload control. To turn optimization off for specific warehouses instead of the whole account, go to the Warehouses tab on that integration's page and disable optimization there.

Turning optimization back on​

Return to Settings > Passthrough and click Resume optimization. Yuki resumes optimizing every warehouse and integration it was covering before you paused - there's nothing else to reconfigure.
