  Most customers combine the **API** (for ad-hoc lookups) with one or more **bulk delivery** channels for analytics and archival needs.\
  Use the `_tracing_id` column to reconcile records consistently across delivery channels.

## Choosing a channel

* Real-time pipelines → API / WSS
* Historical backfills → SFTP / S3 / Azure Blob
* Analytics at scale → Snowflake / Redshift / BigQuery / Delta Share
