Compare identical tables across two SQL Server instances using Python with mssql-python driver and Apache Arrow. Detect missing rows, column mismatches, schema drift, and produce a reconciliation report. 1. Collect connection details for source and target 2. Identify primary key / composite key 3. Detect schema differences 4. Extract data via Arrow for efficient columnar transfer 5. Compare rows and columns 6. Generate reconciliation report | Parameter | Required | Description | |-----------|----------|-------------| | Source server | Yes | Source SQL Server (e.g. prod-server.database.windows.net) | | Source database | Yes | Source database name | | Target server | Yes | Target SQL Server (e.g. staging-server.database.windows.net) | | Target database | Yes | Target database name | | Tables | Yes | Comma-separated schema.table names, or schema. wildcard (e.g. dbo.Orders,dbo.Items or dbo.) | | Auth mode | Yes | sql (user/password) or entra (Azure AD/token) | | Primary key | Auto-detect | Column(s) forming the row identity.
