Look for explicitly defined primary keys, foreign key constraints, and appropriate data types (e.g., using TIMESTAMP instead of VARCHAR for dates). 2.

: Detect duplicate indexes on the same columns, which slow down INSERT and UPDATE operations. Look for explicitly defined primary keys, foreign key
Existing DROP TABLE IF EXISTS or CREATE DATABASE commands that might overwrite local data. Step 4: Execute the Import via CLI
