PHP + MongoDB:查找多个查询

In general, my script is really simple:

  1. findOne by queryX in collectionA
  2. findOne by queryX in collectionB (independent from [1])
  3. Go on with the results from both, 1 and 2.

Now I have the delay: (2) does not start before (1) is finally completed.

Does the mongodb PHP driver provide an option to pass found queries asynchronously?

Let's say one query takes 5 seconds and two queries takes another 5 seconds. This will increase the script's runtime from 10 to 5 in my scenario.

  1. findOne by collectionA
  2. findOne by queryX in collectionB(独立于[1])
  3. 继续使用来自1和2的结果。


    mongodb是不是PHP 驱动程序提供了一个异步传递查找查询的选项吗?

    假设一个查询需要5秒钟,两个查询需要5秒钟。 这将在我的场景中将脚本的运行时间从10增加到5 。

    The MongoDB PHP driver is not capable of doing this today, and infact the MongoDB database itself does not return results out of order either, so this would be really difficult to implement for the driver with out specific support for it at the database level.

    I do believe such functionality is in the works, but it is a major shift, so I don't expect it in the upcoming development series (2.5.x) which will lead to the next production release (2.6.x).
