## Usage

Initialize the extension:
```python
from flask_mysqlpooled import MySQLPooled
    
mysql_pool = MySQLPooled()
mysql_pool.init_app(app)
# or
mysql_pool = MySQLPooled(app)
```

Obtain a cursor:
```python
cursor = mysql_pool.get_db().cursor()
```


Multiple connection example:
```python
import pymysql
from flask import Flask
from flask_mysqlpooled import MySQLPooled

app = Flask(__name__)

mysql_pool_1 = MySQLPooled(app,
                        prefix='MySQLPooled1',
                        host='host1',
                        user='user1',
                        password='password1',
                        db='db1',
                        autocommit=True,
                        cursorclass=pymysql.cursors.DictCursor,
                        mincached=0,
                        maxcached=3)
mysql_pool_2 = MySQLPooled(app,
                        prefix='MySQLPooled2',
                        host='host2',
                        user='user2',
                        password='password2',
                        db='db2',
                        autocommit=True,
                        cursorclass=pymysql.cursors.DictCursor,
                        mincached=0,
                        maxcached=3)

@app.route('/')
def index():
    cursor1 = mysql_pool_1.get_db().cursor()
    cursor2 = mysql_pool_2.get_db().cursor()
    # ...
