ELT vs. reverse ETL: Klaviyo and Amazon S3
ELT (Extract, Load, Transform) moves data from Klaviyo into Amazon S3 for analysis. This is the approach shown on this page, and the one to use for dashboards, reports, and data models.
Reverse ETL works the other direction: it pushes enriched data from Amazon S3 back into Klaviyo. For example, you could sync computed lead scores or customer segments from your warehouse into Klaviyo to personalize outreach.
Weld supports both directions, so you can build a complete data loop between Klaviyo and Amazon S3.
Amazon S3 to Klaviyo- Incremental syncing
- Weld uses incremental syncing where supported by the Klaviyo API, loading only new and updated records to minimize data transfer and warehouse costs.
- Schema handling
- Weld automatically manages schema changes. If Klaviyo adds new fields, they're detected and added to the corresponding Amazon S3 tables.
- Data freshness
- Sync frequency depends on your Weld plan. Most connectors support schedules from every 5 minutes up to daily intervals.
- Security
- All data is encrypted in transit (TLS) and at rest. Weld is SOC 2 Type II compliant and supports IP whitelisting for database connections.
