Laravel 5.2 - Make different Read/Write Connections - php

Question

In laravel 5.2, we wanted to have different connections for read/write, so I followed the advice as provided in laravel documents. But, by default, it was only creating default mysql named connection and not 2 different read/write connections, therefore it was picking the read connection for operations like INSERT/UPDATE.
After debugging, it was found that in DatabaseManager.php file the connection named passed as argument to makeconnection() was mysql and not mysql::read or mysql::write.
Before
config/database.php
'mysql' => [
//we need to have this nested options for both read/write
'read' => [
'host' => env('DB_READ_HOST'),
],
'write' => [
'host' => env('DB_WRITE_HOST'),
],
'host' => env('DB_READ_HOST'),
'username' => env('DB_USERNAME'),
'password' => env('DB_PASSWORD'),
'driver' => 'mysql',
'database' => env('DB_DATABASE'),
'collation' => 'utf8_unicode_ci',
'port' => env('DB_PORT', '3306'),
'charset' => 'utf8',
'prefix' => '',
'strict' => false,
],
File - vendor/laravel/framework/src/Illuminate/Database/DatabaseManager.php
public function connection($name = null)
{
list($name, $type) = $this->parseConnectionName($name);
// If we haven't created this connection, we'll create it based on the config
// provided in the application. Once we've created the connections we will
// set the "fetch mode" for PDO which determines the query return types.
if (! isset($this->connections[$name])) {
$connection = $this->makeConnection($name);
$this->setPdoForType($connection, $type);
$this->connections[$name] = $this->prepare($connection);
}
return $this->connections[$name];
}
So, we have added a small change in the file, after adding this, it's now creating two different connections mysql.read/mysql.write and switching them appropriately according to the given sql operations SELECT,INSERT,UPDATE
Needed you feedback if this is a viable solution ?
After changing the file
config/database.php
'mysql' => [
//we need to have this nested options for both read/write
'read' => [
'host' => env('DB_READ_HOST'),
'username' => env('DB_READ_USERNAME'),
'password' => env('DB_READ_PASSWORD'),
'driver' => 'mysql',
'database' => env('DB_DATABASE'),
'collation' => 'utf8_unicode_ci',
'port' => env('DB_PORT', '3306'),
'charset' => 'utf8',
'prefix' => '',
'strict' => false,
],
'write' => [
'host' => env('DB_WRITE_HOST'),
'username' => env('DB_WRITE_USERNAME'),
'password' => env('DB_WRITE_PASSWORD'),
'driver' => 'mysql',
'database' => env('DB_DATABASE'),
'collation' => 'utf8_unicode_ci',
'port' => env('DB_PORT', '3306'),
'charset' => 'utf8',
'prefix' => '',
'strict' => false,
],
'host' => env('DB_READ_HOST'),
'username' => env('DB_READ_USERNAME'),
'password' => env('DB_READ_PASSWORD'),
'driver' => 'mysql',
'database' => env('DB_DATABASE'),
'collation' => 'utf8_unicode_ci',
'port' => env('DB_PORT', '3306'),
'charset' => 'utf8',
'prefix' => '',
'strict' => false,
],
File - vendor/laravel/framework/src/Illuminate/Database/DatabaseManager.php
public function connection($name = null)
{
list($name, $type) = $this->parseConnectionName($name);
// we check if the $type is read/write and store appropriate connections
if( $type != null ) {
$name .= '.' . $type;
}
//end
// If we haven't created this connection, we'll create it based on the config
// provided in the application. Once we've created the connections we will
// set the "fetch mode" for PDO which determines the query return types.
if (! isset($this->connections[$name])) {
$connection = $this->makeConnection($name);
$this->setPdoForType($connection, $type);
$this->connections[$name] = $this->prepare($connection);
}
return $this->connections[$name];
}
