## Setup
This is init data script for preparing data to learn database index.
```
php artisan migrate --seed
```
It might take a little time because we init 300k row for user_video table.
## Review
1. Use ```EXPLAIN``` statement to see what type of MySQL index and how many rows it perform the queries.
2. Remove/Add index to **user_id** in **user_video** table, too se the different in performance.
3. Query the time range in the **user_video** table
- Index type = range
