## Updates from Langfuse
### 2026-09-14 02:51 UTC: 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 ( ).
We currently work on improving the batch job. All v4 compatible SDKs are not impacted by this. Upgrading SDKs is recommended.

### 2026-09-14 03:52 UTC: investigating
We considerably increased throughput of the batch job to write data into v4 data model. We are currently catching up processing data.

### 2026-09-14 05:14 UTC: monitoring
We're making consistent progress in our backlog and are currently seeing delays of about 60 minutes.
