FAQ
Frequently asked questions
How does Extract handle incremental and full ClickHouse deliveries?
An incremental delivery processes only new or changed data since a stored checkpoint or new date partition, while a full delivery processes the complete selected dataset or date range again. By avoiding repeated processing and writes for the full dataset, incremental deliverys can reduce destination database updates and warehouse compute costs. Destination loading behavior depends on the incoming stream extract mode and the destination load mode; source incremental extraction is not applicable. Extract records run details so teams can verify each delivery.
Can I backfill historical ClickHouse data with Extract?
Historical coverage for ClickHouse: No connector-specific backfill parameter is exposed. Initial historical coverage depends on the stream and provider. Use the setup guide and run details to confirm the available source records and selected settings.
How should teams prepare data for ClickHouse?
Prepare and validate the modeled records before delivery, including any eligibility, consent, or suppression rules required by the workflow. Then use the ClickHouse setup guide and Extract's run-level logs to validate each delivery.
How often can Extract deliver data to ClickHouse?
Extract supports schedules every 15 minutes, hourly, daily, or on a custom cadence. Teams can choose a frequency that matches routine reporting, time-sensitive monitoring, or operational activation needs.
