feat(profiling): Add Perfetto trace format support#5659
Conversation
Add support for ingesting binary Perfetto traces (.pftrace) as profile chunks. The SDK sends an envelope with a ProfileChunk metadata item paired with a ProfileChunkData item containing the raw Perfetto protobuf. Relay decodes the Perfetto trace, extracts CPU profiling samples (PerfSample and StreamingProfilePacket), converts them to the internal Sample v2 format, and forwards both the expanded JSON and the original binary blob to Kafka for downstream processing. Key changes: - New `perfetto` module in relay-profiling for protobuf decoding and conversion to Sample v2 - New `ProfileChunkData` envelope item type for binary profile payloads - Pairing logic to associate ProfileChunk metadata with ProfileChunkData - Raw profile blob preserved through to Kafka for further processing Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>

Add support for ingesting binary Perfetto traces (.pftrace) as profile chunks. This enables Android SDKs to send native CPU profiling data captured via Perfetto's
perf_event_openand in-process stack sampling mechanisms.The SDK sends an envelope with a
ProfileChunkmetadata item paired with a newProfileChunkDataitem containing the raw Perfetto protobuf. Relay decodes the trace, extracts CPU profiling samples (PerfSampleandStreamingProfilePacket), converts them to the internal Sample v2 format, and forwards both the expanded JSON and the original binary blob to Kafka for downstream processing by Snuba/Vroom.Key changes:
