Warmup Worker

POST 
/v1/sql/warmup

Pre-warm a job_v4 worker for the given dataset combination.

Starts a worker subprocess in the background so datasets are loaded into DuckDB memory before the first SQL query arrives (e.g. when a user lands on the viz page or selects datasets in the creation funnel).

  • Returns 202 immediately (fire-and-forget).
  • No-op if a healthy worker already exists for this dataset combination.
  • Errors are silently swallowed on the backend (best-effort).
