-{/* TODO move from https://docs.dagster.io/dagster-plus/references/limits */}
+Dagster+ enforces several rate limits to smoothly distribute the load. Deployments are limited to:
+
+- 40,000 user log events (e.g, `context.log.info`) per minute. This limit only applies to custom logs; system events like the ones that drive orchestration or materialize assets are not subject to this limit.
+- 35MB of events per minute. This limit applies to both custom events and system events.
+
+Rate-limited requests return a "429 - Too Many Requests" response. Dagster+ agents automatically retry these requests.
+
+{/* Switching from [Structured event logs](/concepts/logging#structured-event-logs) to [Raw compute logs](/concepts/logging#raw-compute-logs) or reducing your custom log volume can help you stay within these limits. */}
