Under the hood

Technical considerations.
What to expect.

Incremental syncing: Weld uses incremental syncing where supported by the eSmiley API, loading only new and updated records to minimize data transfer and warehouse costs.
Schema handling: Weld automatically manages schema changes. If eSmiley adds new fields, they're detected and added to the corresponding MotherDuck 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.
