Under the hood

Technical considerations.
What to expect.

Incremental syncing
Weld uses incremental syncing where supported by the BigCommerce API, loading only new and updated records to minimize data transfer and warehouse costs.
Schema handling
Weld automatically manages schema changes. If BigCommerce 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.
