QLI is Incomplete

If not all queries show up after being ingested via QLI, there is a known limitation concerning entities (schemas, tables) containing special characters. Refer to the Dremio Query Log Ingestion section for more details.

Sampling Errors

If you encounter errors while sampling some tables, it could be due to a limitation when sampling tables with column names that are Dremio reserved keywords. These tables should be renamed, or removed from Sampling. Please refer to the Dremio Data Sampling section for more details.

Migrating to Open Connector Framework from Legacy Connector

Users of the legacy, native Dremio connector are encouraged to migrate to the Dremio OCF Connector. Refer to Migrate Native File System Sources to OCF Connectors.
