# Warm Up RHEED Stream Worker

> Check whether a RHEED processing worker is ready and trigger a warm-up if not

Checks whether a RHEED processing worker is ready. Returns `true` if a worker is ready, or `false` otherwise (in which case a warm-up is triggered). Call this before starting a stream to reduce cold-start latency.

## Response

Returns a boolean: `true` if a processing worker is ready, `false` otherwise.
