Upload files

You can upload files directly into Querio without connecting an external database.

Uploaded files are ingested into a managed datasource called uploads. Once uploaded, they are immediately available to query and analyze like any other datasource.

Supported formats

• CSV
• TSV
• Parquet
• JSON

How to upload

1. Go to the Catalog for your workspace
2. Click Upload files in the header
3. Drag and drop files into the dialog, or click to browse
4. Querio ingests each file and creates a table named after the file

Each file becomes its own table in the uploads datasource. The table name is derived from the filename.

Limits

• 100MB per file
• 100MB total per batch
• 10 million rows per file
• 1,024 columns per file

After uploading

Once ingestion is complete, the table appears in your Catalog under the uploads datasource. You can query it immediately in an Explore session.

If Querio detects that the data structure or column descriptions have drifted from what the catalog says, it will flag this and suggest an update.

Notes

• Only one file can be written to the uploads datasource at a time per workspace. If multiple files are uploaded at once, they are ingested sequentially.
• File uploads are available for workspace v2 (fs-mode) workspaces.
