是否有一个轻量级的，可嵌入的键/值数据库？ （像饮食couchdb） [英] Is there a lightweight, embeddable, key/value database? (something like diet couchdb)

问题描述

我想知道是否有一个轻量级的，可嵌入的键/值数据库。

像一个轻量级的Couchdb（RESTful，键/值等）

解决方案

/ div>

在CouchDB wiki的相关项目页面的替代方法下，他们提到一些类似的项目：

• Feather DB ^* CouchDB克隆在java中。


• StrokeDB ^* 一个用Ruby编写的CouchDB类数据库，可以更容易地嵌入到Ruby应用程序中。


• mongoDB 高性能，开放源代码，无模式的面向文档的数据库。

当然还有东京

还有 neo4j ，它是一个用于java的图形数据库。

当然，CouchDB和其他一些功能的一部分不仅仅是能够存储键/值对，但高容量，复制，特别是视图，这基本上是在文档上运行查询的方式。

如果你只需要一个简单的键/值数据存储，您可以将其嵌入到程序中，而不必持有数据的数据，这是值得尊敬的

如果不了解你的需求（编程语言，并发性要求，数据量等等），有点难以回答， 。

^* 网站在撰写本文时似乎不起作用。

I was wondering if there was a lightweight, embeddable, key/value database out there.

Something like a lightweight Couchdb (RESTful, key/value, etc) where you just send it the key and it responds with appropriate values.

Thanks!

解决方案

On the Related Projects page of the CouchDB wiki, under "Alternatives" they mention some similar projects:

• Feather DB^* CouchDB clone in java.
• StrokeDB^* A CouchDB-like database written in Ruby to make embedding into Ruby apps easier.
• mongoDB A high-performance, open source, schema-free document-oriented database.

And of course Tokyo Cabinet which has already been mentioned.

There's also neo4j which is a "graph database" for java.

Of course, part of the power of CouchDB and some of the others is not just being able to store key/value pairs, but the high capacity, replication, and in particular views, which are basically the way of running queries over your documents.

If you just needed a simple key/value datastore that you can embed into your program, that doesn't have to hold gigs of data, the venerable GDBM might suit your needs.

A little hard to answer without knowing a bit more about your needs (programming language, concurrency requirements, data volumes and such).
