## 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
