<p>Is there a way to disable WAL replay on crash for Prometheus?</p>
<p>It takes a while for a pod to come back up due to WAL replay:</p>
<p>We can afford to lose some metrics if it meant faster recovery after the crash.</p>

<p>Not specifically that I'm aware of. You would have to <code>rm -rf wal/</code> before starting Prom. Usually better to run multiple via Thanos or Cortex than to go down this path.</p>
