我有一个包含 9 种类型的节点、9 种关系类型和 50 个条目（节点和关系）的数据库，当我尝试保存一个新节点时，库在函数中执行 140 次查询。

我的 PHP 代码：

$iUser = new User();
$iUser->setEmail($mail);
$iUser->setName($name);
$this->getEntityManager()->persist($iUser); // <-- It's do 140 queries
$this->getEntityManager()->flush();

类定义

/** @OGM\Node(label="User") */
class User {
    @OGM\GraphId()
    private $id;
    /** @OGM\Property(type="string") */
    private $name;
    /** @OGM\Property(type="string") */
    private $mail;

    // Set, genters, ...
}

库版本：

graphaware/neo4j-bolt                1.10.0
graphaware/neo4j-common              3.5.0
graphaware/neo4j-php-client          4.8.1
graphaware/neo4j-php-ogm             1.0.0-RC5

查询一直重复数据库中的关系和其他ID，相同的查询更改名称关系或ID，查询是：

查询

MATCH (n) WHERE id(n) = {id} RETURN size((n)<-[:`<name relation>`]-()) AS users     

Parameter: array:1 [▼
  "id" => 189
]

MATCH (n) WHERE id(n) = {id} MATCH (n)<-[vendor_neo4j_entity_roleentity_users:`HAVE_ROL_GLOBAL`]-(vendor_neo4j_entity_haverolglobalrelationship) RETURN {target: startNode(vendor_neo4j_entity_roleentity_users), re: vendor_neo4j_entity_roleentity_users} AS vendor_neo4j_entity_roleentity_users 

Parameter: array:1 [▼
  "id" => 189
]
