Langfuse: Delayed Ingestion for non v4 SDKs
Affected components: Ingestion API
Timeline of updates
- investigating
We currently experience an ingestion delay of old SDKs by 3 hours. This is due to performance issues in our batch job which moves data into the v4 data model (https://langfuse.com/changelog/2026-08-17-langfuse-v4). We currently work on improving the batch job. All v4 compatible SDKs are not impacted by this. Upgrading SDKs is recommended.
- investigating
We considerably increased throughput of the batch job to write data into v4 data model. We are currently catching up processing data.
- monitoring
We're making consistent progress in our backlog and are currently seeing delays of about 60 minutes.
- resolved
The incident has been resolved.
