Too bad: "PHP has encountered an Access Violation at 7C81BD02"
There are so many jokes one could make. Since it's HN, I won't.
I like how you joke about joking, and that's enough to be funny.
just a note for people who come across this and are confused: queries in MongoDB use a much more concise document-based query language, not map/reduce. map/reduce in MongoDB is just for aggregations / ETL type operations
is there any chance MongoDB will introduce some form of transaction support?
The MongoDB query looks just like the execution plan that'd be generated behind the scenes by the query evaluator of any relational database. Except, of course, the MongoDB query isn't optimized nearly as much as the query plan generated by the relational database would be.
