## Notable Changes

### permit streaming prepare statement result

Like queryStream, execute command can now be streamed as well for huge resultset, to avoid charging the whole resultset in memory.\
Example :

```js
const prepare = await shareConn.prepare('SELECT * FROM mysql.user where host = ?');
const stream = prepare.executeStream(['localhost']);    
try {
  for await (const row of stream) {
    console.log(row);
  }
} catch (e) {
  queryStream.close();
}
prepare.close();
```
