Previously, the progress bar updated only after completing an entire table. For large tables such as LIBARC, this could make the application appear to have stopped responding. Phase 10 updates the interface while rows are being exported.

Phase 24 — Query Performance Diagnostics
Builds on Phase 23.
- Adds a read-only index diagnostic section to the EXPLAIN inspector. Flags full scans with/without candidate indexes, and optimizer steps without a selected index.
- Adds per-step tabular EXPLAIN baseline comparisons for access type, selected index, possible indexes, estimated rows, filtered percentage, and Extra information.
- Adds Copy Diagnostics to copy SQL, plan observations, index analysis, and baseline differences.
- Preserves the Phase 23 query plan history and existing database management features.
Important
The application has not been compiled in Xcode or tested against MySQL in this environment. The analysis uses optimizer estimates, not measured timings. It intentionally does not generate or apply CREATE INDEX statements. Compare plans only for equivalent schema/data conditions.
