是否有内存中的键/值存储可以通知外部实体更改？
我读过有关内存中键/值存储的内容，但从未实际使用过。我这个没受过教育的人首先想到的是 CouchDB 和 memcached（我知道 CouchDB 不一定在内存中，但经常这样使用）。
我正在寻找支持基本脚本编写的内存存储之一，以便我可以向外部实体（通过 RESTful API）通知更改。一些初步研究表明，CouchDB 支持名为 更改通知 的内容
Memcached 似乎不支持这种类型功能，并且是一种更通用的仅存储服务（再次，我的无知可能会在这里暴露出来）。
有人有这样做的经验吗？对于潜在的陷阱或令人头痛的问题，您有什么智慧的话吗？是否还有我未列出的其他软件支持这些功能？
I have read about in-memory key/value stores but have never actually utilized one. The first that come to my uneducated mind are CouchDB and memcached (I know CouchDB isn't necessarily in-memory, but is often used as such).
I am looking for one of these in-memory stores that support basic scripting, such that I could notify an external entity (through a RESTful API) of a change. Some preliminary research reveals that CouchDB supports something called Change Notifications
Memcached does not seem to support this type of feature, and is a more general storage-only service (again, my ignorance may shine through here).
Does anyone have any experience doing this? Any words of wisdom for potential pitfalls or headaches? Is there some other software I didn't list that would support these features?

membase 实现memcached 点击协议以流式传输所有发生的突变。我们在此基础上构建了很多东西（复制是一个用例）。
membase implements the memcached tap protocol to stream out all mutations as they occur. We build a lot of stuff on top of that (replication is a use case).
将 RAM 安装为磁盘并将其作为数据目录启动 couchdb 怎么样？
您可以将 ram 磁盘安装为：
并更改 couchdb 配置文件以将数据存储在该目录中。
启动 couchdb 并放松！
How about mounting RAM as disk and starting couchdb with that as data dir?
You can mount a ram disk as:
And change the couchdb configuration file to store the data in that directory.
Start couchdb and relax!
