在具有中央ElastiCache（redis）羣集的多個AWS EC2實例上運行分佈式SF3.3應用程序。具有Doctrine 2二級緩存和Symfony 3.3的多區域緩存

每個EC2實例還運行用於Doctrine元和查詢緩存的本地Redis實例。

此應用程序使用Doctrines Second Level Cache，從功能的角度來看，它工作得非常好。但是AWS上的性能很差（900-1200毫秒頁面加載），這是因爲它在我們的許多頁面上需要加載的我們的Country和VatRate實體所進行的400多次緩存調用。

由於這些Country和VatRate實體很少發生變化，我想通過使用二級緩存中定義的不同區域來利用本地Redis實例和ElastiCache進行結果緩存。這應該可以減少400+緩存調用的延遲問題，因爲在單個頁面加載時運行時間小於100毫秒。閱讀文檔這一切似乎都是可能的，只是不完全確定如何使用Symfony和PHP-Cache進行配置。

當前配置的一個例子：

應用/配置/ config.yml

導致

Type error: Argument 1 passed to Doctrine\ORM\Cache\DefaultCacheFactory::setRegion() must be an instance of Doctrine\ORM\Cache\Region, instance of Cache\Bridge\Doctrine\DoctrineCacheBridge given,

不太確定從哪裏開始，一直在測試這裏工作：https://github.com/doctrine/DoctrineBundle/blob/74b408d0b6b06b9758a4d29116d42f5bfd83daf0/Tests/DependencyInjection/Fixtures/config/yml/orm_second_level_cache.yml但缺乏配置文件，這使得它更具挑戰性！

您收到的錯誤消息完全反映了您的問題的根源。你逝去的DoctrineCacheBridge實例（基礎類的doctrine.orm.default_result_cache）當Doctrine\ORM\Cache\Region接口的情況下，預計：

  second_level_cache: 
       #... 
       regions: 
        local: 
         type: service 
         service: "region_service_not_cache_service" # Here is a Region instance expected 
        remote: 
         type: service 
         service: "region_service_not_cache_service" #Here is a Region instance expected

在你以前的配置doctrine.orm.default_result_cache緩存服務被設置爲通過region_cache_driver設置默認緩存。 \Doctrine\ORM\Cache\DefaultCacheFactory在航班上生成DefaultRegion的實例（因爲沒有預先配置）並將默認緩存提供給它們。

後一種配置預計會有預先配置的區域，並且可以通過多種方式進行修復。我建議的下一個：

dbal: 
    # .. params 

orm: 
    #... 
      second_level_cache: 
       #... 
       regions: 
        local: 
         type: default 
         cache_driver: 
          type: service 
          id: "doctrine.orm.default_query_cache" # NOTE that this is the service id of your local cache generated by PHP-Cache Bundle 
        remote: 
         type: default 
         cache_driver: 
          type: service 
          id: "doctrine.orm.default_result_cache" # NOTE that this is the service id of your remote cache generated by PHP-Cache Bundle

在這裏，你告訴原則下local和remote鍵創建2個DefaultRegion地區，並通過local_cache和remote_cache給他們相應。

而且最好返回region_cache_driver以其他方式DefaultRegion S于飛行中產生的前值將使用array緩存：

  second_level_cache: 
       enabled: true 
       region_cache_driver: 
        type: service 
        id: doctrine.orm.default_result_cache

謝謝，問題是試圖正確地創建這些服務。正如我對待嘗試的配置 - app/config/config.yml的todo評論中所述 – Nick

與PHP-緩存庫多打轉轉之後，很明顯從看在CacheBundle編譯器，它將只支持配置中的一個DoctrineBridge實例。 https://github.com/php-cache/cache-bundle/blob/master/src/DependencyInjection/Compiler/DoctrineCompilerPass.php

解決方案是創建我自己的編譯器，不漂亮，但它似乎工作。

SRC /的appbundle/DependencyInjection /編譯器/ DoctrineCompilerPass.php

namespace AppBundle\DependencyInjection\Compiler; 

use Cache\Bridge\Doctrine\DoctrineCacheBridge; 
use Cache\CacheBundle\Factory\DoctrineBridgeFactory; 
use Symfony\Component\DependencyInjection\Compiler\CompilerPassInterface; 
use Symfony\Component\DependencyInjection\ContainerBuilder; 
use Symfony\Component\DependencyInjection\Reference; 

class DoctrineCompilerPass implements CompilerPassInterface 
{ 
    /** @var ContainerBuilder */ 
    private $container; 

    public function process(ContainerBuilder $container) 
    { 
     $this->container = $container; 

     $this->enableDoctrineCache('local'); 
     $this->enableDoctrineCache('remote'); 
    } 

    private function enableDoctrineCache(string $configName) 
    { 
     $typeConfig = [ 
      'entity_managers' => [ 
       'default' 
      ], 
      'use_tagging' => true, 
      'service_id' => 'cache.provider.' . $configName 
     ]; 

     $bridgeServiceId = sprintf('cache.service.doctrine.%s.entity_managers.bridge', $configName); 

     $this->container->register($bridgeServiceId, DoctrineCacheBridge::class) 
      ->setFactory([DoctrineBridgeFactory::class, 'get']) 
      ->addArgument(new Reference($typeConfig['service_id'])) 
      ->addArgument($typeConfig) 
      ->addArgument(['doctrine', $configName]); 
    } 
}

SRC /的appbundle/AppBundle.php

use AppBundle\DependencyInjection\Compiler\DoctrineCompilerPass; 
use Symfony\Component\DependencyInjection\ContainerBuilder; 
use Symfony\Component\HttpKernel\Bundle\Bundle; 

class AppBundle extends Bundle 
{ 
    public function build(ContainerBuilder $container) 
    { 
     parent::build($container); 

     $container->addCompilerPass(new DoctrineCompilerPass()); 
    } 
}

應用/配置/ config.yml

doctrine: 
    dbal: 
    # ... params 

    orm: 
     auto_generate_proxy_classes: "%kernel.debug%" 
     entity_managers:

       auto_mapping: true 
       second_level_cache: 
        enabled: true 
        regions:

          cache_driver: 
           type: service 
           id: cache.service.doctrine.remote.entity_managers.bridge 
         local: 
          cache_driver: 
           type: service 
           id: cache.service.doctrine.local.entity_managers.bridge 

cache_adapter: 
    providers: 
     local: 
      factory: 'cache.factory.redis' 
      options: 
       host: '%redis_local.host%' 
       port: '%redis_local.port%' 
       pool_namespace: "local_%hash%" 
     remote: 
      factory: 'cache.factory.redis' 
      options: 
       host: '%redis_result.host%' 
       port: '%redis_result.port%' 
       pool_namespace: 'result' 

cache: 
    doctrine: 
     enabled: true 
     use_tagging: true 
     metadata: 
      service_id:   'cache.provider.local' 
      entity_managers: [ default ] 
     query: 
      service_id:   'cache.provider.local' 
      entity_managers: [ default ]

儘管這看起來在某種程度上有效，但是當緩存中可能存在某些內容時，本地緩存調用會導致500錯誤，從而導致一些不一致。總的來說，我試圖彎曲二級緩存，超過它的設計目標。
