Add RUM Profiler data model to rum-events-format by BeltranBulbarellaDD · Pull Request #325 · DataDog/rum-events-format

BeltranBulbarellaDD · 2025-12-02T13:39:13Z

This PR adds the Profiling data model, making it consistent with RUM and Session Replay Schema.

Structure:

profiling
│   _common-schema.json
└───browser/
│      profile-event-schema.json
│      profiler-trace-schema.json
└───mobile/
       profile-event-schema.json

browser/profile-event-schema.json: Browser-specific payload schema extending _common-schema.json with browser-specific fields (format, _dd.clock_drift) and the wall-time trace.

mobile/profile-event-schema.json: Mobile-specific profile event extending _common-schema.json with the vital property.

Samples where taken from the test:performance e2e test in Browser-SDK repo

In this Browser PR we can see how they will be used.

+  "title": "ProfileEventPayload",
+  "type": "object",
+  "description": "Schema of the Profile Event payload.",
+  "required": ["event", "wall-time.json"],


strictly speaking, Mobile SDKs don't have wall-time.json, but at the same time event is passed in the multipart-form format, next to the recording binary unlike in case of Browser SDK

I see, should I remove this ProfileEventPayload as it's too platform-specific?

In the browser, the event is also sent as multipart form data, alongside the profiler trace binary. The backend does not expect a ProfileEventPayload type. We should remove it.

Looks good for Mobile 👍 I left few comments.

Discussed this build failure for android-sdk with @BeltranBulbarellaDD .

TL;DR. Kotlin Poet can't create a class with field name wall-time.json, because it contains a dot. In kotlin you can't have dots in field names even val "wall-time.json": Int.

In the current CI run our session replay module fetched new profiling schema files and started checking them. I'll fix it.

IIUC wall-time.json is needed here. So we probably should leave it as it is. If it comes to Android at some point, we will have to deal with it.
