Hi, I recently came across the post which specified that Mongoid will no longer use the official Mongo Ruby driver, but will instead use new Moped driver and also will be using the Origin gem to build MongoDB queries. After this I combed through the archives of this list and also looked at the issues list of mongoid to see if there has been any discussion or announcement about the beginning on these two new tools, but found nothing.

So here are a few questions related to that : Please note that I am not criticizing the work with these question but only trying to understand the idea behind these two new gems.

All in all I am very excited to see so much activity around Mongoid. What is the rationale behind it, considering that Mongo has an official ruby driver and maintaining a new driver will involve considerable work with every new feature of MongoDB? Would the pure ruby implementation be really faster than what the official driver provides?

Or is there a plan to bring in native implementation sometime in the future. From a brief glance of the Origin code it doesn't seem to depend on any particular driver. Creating a query using Mongoid 3.

If is false, the query returns only the documents that do not contain the field. Beside the difference between existence and is null , you could have a time zone problem. However, the MongoDB shell will use whatever time zone is currently in effect when it converts to a timestamp:.

Note the Z. Also, since you're only looking at a count, you can leave out the second argument to find in the MongoDB shell to simplify things. Fix the problems that tirdadc and I have pointed out and see if you get the same results in both cases. If you don't, then start building both queries piece by piece until they produce different results and you'll know where the problem lies.

Don't forget to include the sorting options from the start and compare the returned documents IDs rather than just the counts.
