Export via Blob Storage Integration

You can create schedule exports to a Blob Storage, e.g. S3, GCS, or Azure Blob Storage, for traces, observations, enriched observations, and scores.

Those exports can run on an hourly, daily, or weekly schedule. Navigate to your project settings and select Integrations > Blob Storage to set up a new export. Select whether you want to use S3, a S3 compatible storage, Google Cloud Storage, or Azure Blob Storage.

Start exporting via Blob Storage

To set up the export navigate to Your Project > Settings > Integrations > Blob Storage.

Fill in the settings to authenticate with your vendor, enable the integration, and press save. Within an hour an initial export should start and continue based on the schedule you have selected. The export supports CSV, JSON, and JSONL file formats. Read our blob storage documentation for more information on how to get credentials for your specific vendor.

Export source (Langfuse v4)

Blob Storage integrations now include an Export Source selector. New integrations default to Enriched observations (recommended) (trace attributes are directly set on observations).

This source uses enriched observations with trace attributes and provides significantly better export performance. Scores are always included, regardless of the selected source.

Available options:

• Traces and observations (legacy)
• Traces and observations (legacy) and enriched observations
• Enriched observations (recommended)

Upgrade path for existing configurations

Existing integrations continue to use Traces and observations (legacy) until changed.

To migrate safely:

1. Switch to Traces and observations (legacy) and enriched observations.
2. Validate downstream jobs and data consumers while both sources are exported (this mode creates duplicate records by design).
3. Switch to Enriched observations (recommended) once validation is complete.

For rollout details, see the Simplify for Scale changelog.

Alternatives

You can also export data via:

• UI - Manual batch-exports from the Langfuse UI
• SDKs/API - Programmatic access using Langfuse SDKs or API
