Session: How to Get the Current Session Node
When working in a RavenDB cluster, a database can reside on multiple nodes.
When the client needs to send a request to the server, it can have several nodes to choose from.
The client uses this logic
to determine which node to send the request to.
Learn more about load balancing the client requests in this overview.
Use the getCurrentSessionNode
method from the advanced
session operations
to find out what is the current node that the session sends its requests to.
Syntax
public function getCurrentSessionNode(): ServerNode;
Return Value
The return value of getCurrentSessionNode
is a ServerNode
object
class ServerNode
{
private ?Url $url = null;
private ?string $database = null;
private string $clusterTag;
private ?ServerNodeRole $serverRole = null;
public function __construct()
{
$this->serverRole = ServerNodeRole::none();
}
// ... getters and setters
}
class ServerNodeRole
{
public static function none(): ServerNodeRole;
public static function promotable(): ServerNodeRole;
public static function member(): ServerNodeRole;
public static function rehab(): ServerNodeRole;
}
Example
$serverNode = $session->advanced()->getCurrentSessionNode();
echo $serverNode->getUrl();
