问题描述
Redis 非常快.在我的机器上的大多数情况下，它与 node.js 中的原生 Javascript 语句或函数调用一样快.在 node.js 中编写常规 Javascript 代码很容易/无痛，因为不需要回调.我不明白为什么使用 node.js 在 Redis 中获取/设置键/值数据不应该那么容易.
Redis is very fast. For most part on my machine it is as fast as say native Javascript statements or function calls in node.js. It is easy/painless to write regular Javascript code in node.js because no callbacks are needed. I don't see why it should not be that easy to get/set key/value data in Redis using node.js.
假设 node.js 和 Redis 在同一台机器上，是否有任何 npm 库允许使用阻塞调用与 node.js 上的 Redis 交互?我知道这必须是一个与 V8 接口的 C/C++ 库.
Assuming node.js and Redis are on the same machine, are there any npm libraries out there that allow interacting with Redis on node.js using blocking calls? I know this has to be a C/C++ library interfacing with V8.
推荐答案
我想您想确保所有的 redis 插入操作都已执行.为此，您可以使用 MULTI 命令插入键或执行其他操作.https://github.com/mranney/node_redis 模块将在多对象中推送的命令排队，并且相应地执行它们.
I suppose you want to ensure all your redis insert operations have been performed. To achieve that, you can use the MULTI commands to insert keys or perform other operations.The https://github.com/mranney/node_redis module queues up the commands pushed in multi object, and executes them accordingly.
这样你只需要一个回调，在 exec 调用结束时.
That way you only require one callback, at the end of exec call.
