Object storage test data management

Those files are often forgotten copies of production data, so a test-data process should read them in place, mask them, and help retire them.

What test data management needs here

• Reading Parquet and CSV in place, with declared table names so that data-derived file names never leave your network.
• Least-privilege read access; object stores rarely expose permissions in a way a client can verify.
• Declared relationships between files, because files carry no foreign keys.

How DataNivra approaches it

• File sets map operator-declared logical tables to paths; undeclared names become opaque hashes.
• Where read-only access cannot be introspected, the agent requires an explicit attestation and fails closed without it.
• Whatever the system, row-level work happens in the DataNivra agent inside your network: only metadata, aggregates and evidence reach DataNivra Cloud.
