Import And Migration Studio

Import/export and migration planning are separate workflows: import moves data into a table, while Migration Studio plans schema and data verification steps.

Import

Preview incoming CSV, TSV, JSON, and NDJSON data before writing it. Check inferred columns, target table names, null handling, and delimiter/quote settings before running an import.

Migration Studio

Migration Studio compares source and target metadata, builds preview SQL, and surfaces destructive changes before execution. The reusable planning and data-diff primitives live in irodori-migration; the desktop app supplies live connections, jobs, cancellation, and UI review.

Verification

Use row counts, checksums, bucket fingerprints, and row-level diffs to verify a migration. For very large tables, prefer bucketed verification first and inspect only the failed buckets.
