DuckDB

Local file-backed analytics for ad-hoc data.

At a glance

Setup

1. Open Connect source

   In the app, go to Data sources and choose Connect source. Open the Warehouses tab and select DuckDB.

2. Upload your file

   Select your file. Queringo reads the columns, infers types, and turns the file into a queryable source.

3. Save the connection

   Queringo tests the connection before saving, then discovers the schema. PII is flagged and masked by default during discovery.

Preparing your file

1. Export your data to a .duckdb file or one of DuckDB's supported file formats (Parquet, CSV).
2. Upload the file in the DuckDB connection form. Queringo loads it into a sandboxed engine for querying.

Test the connection

Queringo runs a connection test as part of saving. If it fails, the error message indicates what to check (credentials, network reachability, or scope). From Data sources, you can re-run Test connection on the source row any time, for example after rotating a secret or changing network rules.

Edit or rotate

Uploaded files do not have stored credentials. To refresh the data, re-upload the file as a new source.
