我想知道是否有人可以告诉我MongoDB或CouchDB是否已经为生产环境做好了准备。
我现在正在研究这些存储解决方案(目前我更喜欢MongoDB)，但是这些项目还很年轻，所以我预见到我将不得不非常努力地说服我的经理，我们应该采用这种新技术。
我想知道的是:
现在谁在生产环境中使用MongoDB或CouchDB ? 你如何使用MongoDB/CouchDB? 当你采用这种新的存储机制时，你遇到了什么问题(如果有的话)(你是如何克服它们的)? 你是如何处理你不得不面对的移民问题的? 你有任何好的或坏的经验，这些解决方案，你想分享吗?
当前回答
MongoDB在授权给企业方面存在一些问题，我不确定细节，但我们的法律部门不明确地告诉我们，我们不允许在我们的任何产品中使用MongoDB。
其他回答
我们将CouchDB作为MySQL的替代品运行在我们的商店(70.0000个商品/商店，所有商品的属性总数为400万个，商品之间的交叉连接)。
我们的目标是:
从master-db轻松复制到具有不同文档的多个客户端。 快速预计算数据，比如“这个属性和那个过滤器有多少部分符合这些条件”
事实:
我们的商店现在运行得比使用MySQL快得多(MySQL数据库需要额外的1-3天的预计算(因此每月更新两次)，使数据为产品计数和过滤做好准备，CouchDB需要5个小时，所以我们可以每晚更新产品数据) 设置(过滤)数据分布和备份到商店节点是快速和容易的
但也:
Understanding map/reduce and the limits of not having joins is quite hard No operation on data like "delete where" or "update where" without external programs Replication works well, unless there is a problem; then it's really hard to find out what was the reason (for beginners) The installation of CouchDB without binaries (yes there are a some in the wild, but not for every OS/version) could be hard, if you are not a Linux geek. But the CouchDB Community is helpful (#couchdb), and luckily there are companies out there (cloudant, iriscouch) that offer services from free to big business. CouchDB is moving forward, so there are a lot of changes (improvements) going on that might change they way you work. But basic things remain stable.
结果是: MySQL作为数据创建和维护的数据库是可靠的，易于理解和处理。我认为我们不会改变这一点。 但我也不想错过CouchDB视图的强大功能和复制设置的便利性。
在工作了几个月之后，生产沙发有时会因为错误配置和忘记日志(视图构建花费太长时间或挂起，复制停止)而造成麻烦，但从未丢失数据，并且总是可以轻松重置。
下面是mongoDB生产部署站点的列表
The New Yorks Times: Using it in a form-building application for photo submissions. Mongo's lack of schema gives producers the ability to define any combination of custom form fields. SourceForge: is used for back-end storage on the SourceForge front pages, project pages, and download pages for all projects. Bit.ly Etsy IGN: powers IGN’s real-time traffic analytics and RESTful Content APIs. Justin.tv: powers Justin.tv's internal analytics tools for virality, user retention, and general usage stats that out-of-the-box solutions can't provide. Posterous Intuit Foursquare: Sharded Mongo databases are used for most data at foursquare. Business Insider: Using it since the beginning of 2008. All of the site's data, including posts, comments, and even the images, are stored on MongoDB. Github: is used for an internal reporting application. Examiner: migrated their site from Cold Fusion and SQL Server to Drupal 7 and MongoDB. Grooveshark: currently uses Mongo to manage over one million unique user sessions per day. Buzzfeed Discus Evite: Used for analytics and quick reporting. Squarespace Shutterfly: is used for various persistent data storage requirements within Shutterfly. MongoDB helps Shutterfly build an unrivaled service that enables deeper, more personal relationships between customers and those who matter most in their lives. Topsy Sharethis Mongohq: provides a hosting platform for MongoDB and also uses MongoDB as the back-end for its service. Our hosting centers page provides more information about MongoHQ and other MongoDB hosting options.
