 - **Full migration**: Improved to save global `last_key` after completing all partitions
 - **State tracking**: Moved from `migration_state.json` to PostgreSQL table `migration_state`
 - **Query performance**: Added `min_mysql_id` parameter to `fetch_consolidation_keys_after()` for optimization
-- **Documentation**: Updated README.md, MIGRATION_WORKFLOW.md, QUICKSTART.md with current implementation
+- **Configuration**: Renamed `BATCH_SIZE` to `CONSOLIDATION_GROUP_LIMIT` to better reflect what it controls
+- **Configuration**: Added `PROGRESS_LOG_INTERVAL` to control logging frequency
+- **Configuration**: Added `BENCHMARK_OUTPUT_DIR` to specify benchmark results directory
+- **Documentation**: Updated README.md, MIGRATION_WORKFLOW.md, QUICKSTART.md, EXAMPLE_WORKFLOW.md with current implementation
 
 ### Removed
 - **migration_state.json**: Replaced by PostgreSQL table
@@ -70,6 +73,7 @@ If you have an existing installation with `migration_state.json`:
 - `--state-file` parameter removed from incremental migration (no longer uses JSON)
 - `--use-id` flag removed (consolidation-based approach is now default)
 - Incremental migration requires full migration to be run first
+- `BATCH_SIZE` environment variable renamed to `CONSOLIDATION_GROUP_LIMIT` (update your .env file)

 ## Performance Tips
 
 1. **Migration**
-   - Aumentare `BATCH_SIZE` per meno transazioni (es. 50000)
+   - Aumentare `CONSOLIDATION_GROUP_LIMIT` per processare più chiavi per batch (default: 40000)
+   - Aumentare `PROGRESS_LOG_INTERVAL` per ridurre logging (default: 10000)
    - Disabilitare indici durante migrazione se possibile (non implementato)
 
 2. **Queries on JSONB**
