缓存学说结果 Symfony2

问题描述

我正在做一个 Symfony2 项目.我的项目使用数据库来存储数据和 Doctrine2 来检索该数据.

I am working on a Symfony2 project. My project uses database to store the data and Doctrine2 to retrieve that data.

随着数据库中数据的增长，查询变得非常缓慢，整个 Web 应用程序需要大约 2 分钟才能加载或根本不加载.

As the data within the database has grown the queries became very slow and the whole web app takes about 2 mins to load or does not load at all.

我可以看到自己修复此问题的唯一方法是缓存一些查询结果，但我该怎么做.除非有不同的处理方式.

The only way I can see my self fixing this is to cache some queries results but how can I do that. Unless there is different way of dealing with such issue.

推荐答案

您需要安装并配置您的缓存驱动程序 configuration(result_cache_driver 对你来说很重要).完成此操作后，您可以通过设置 useResultCache(true)

You need to have your cache driver installed and configured in doctrine configuration (result_cache_driver is important in your case). Once you have this done you can make Doctrine to use result cache by setting useResultCache(true)

$cachedResult = $doctrine->getManager()
    ->createQueryBuilder()
    ->(...)
    ->useResultCache(true)
    ->(...)

注意:默认情况下，在开发环境中，不会使用结果缓存

NOTE: by default, in dev environment, result cache won't be used

EDIT:因为您使用的是 DBAL 而不是使用 ORM - SymfonyDoctrineBundle 不支持这种开箱即用的缓存，但您可以按照 自己添加此支持这个详细指南

EDIT: as you're using DBAL and not using ORM - SymfonyDoctrineBundle doesn't support this kind of cache out of the box, but you can add this support by yourself by following this detailed guide
