Browse Source Schema
Where: sidebar → Source Schema.
Choose a discovered source
Find the source and crawler in the list. Review the latest snapshot and Last crawled information, then select Browse schema.
Navigate its structure
Select a schema or database, then a table or view. Use search and sorting to locate a relation. Review columns, native types, nullability, and any constraints or DDL provided by the connector.
Check freshness before authoring
Confirm that expected columns exist before configuring a pipeline. Use Scan again when a fresh scan is needed and you have permission. Wait for completion and inspect the new snapshot.
Interpret missing information
- No snapshot: configure and run a crawler first.
- Failed latest crawl: the explorer may show the last successful snapshot; it is not evidence that the failed scan succeeded.
- No constraints or DDL: discovery output depends on the source and connector. Absence in the explorer is not proof that the source has no constraints.
Source metadata is not a row preview and is not a managed table in the Data Catalog. To materialize source rows, create and execute a pipeline.
