Code Review

This pull request introduces a new "Platform Events" page to the Ray dashboard, allowing users to view cluster-level events. The changes include the addition of a new API service, TypeScript type definitions, routing configurations, and UI components such as a dedicated events table and severity-based status chips. Feedback focuses on optimizing the use of React state for static values and improving the table's layout and data handling for long event messages.

HEAD errors mark feature enabled

Medium Severity

getPlatformEventsEnabled treats any failed head except HTTP 404 as enabled. Network failures and 5xx responses set platformEventsEnabled to true, so the Platform Events nav item can appear when the endpoint is unreachable or failing.

+export const getPlatformEventsEnabled = async (): Promise<boolean> => {
+  try {
+    await head("api/v0/platform_events");
+    return true;


HEAD runs full events handler

Medium Severity

Each dashboard load calls head on api/v0/platform_events to gate the nav. On aiohttp, HEAD on a GET route still runs the same handler, which sorts up to 1000 events and builds the full JSON body. That work runs on every visit even when the user never opens Platform Events.
