Technical considerations.
What to expect.
- Incremental syncing
- Weld uses incremental syncing where supported by the Fourth API, loading only new and updated records to minimize data transfer and warehouse costs.
- Schema handling
- Weld automatically manages schema changes. If Fourth adds new fields, they're detected and added to the corresponding ClickHouse 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.
