| Description |
DescriptionIn 4.4 we're adding a feature called user-defined functions (UDFs), which lets users embed Javascript in an aggregation pipeline using the new $function and $accumulator operators. This removes one of the last few things that mapReduce can do that aggregation pipelines can't, so we can add more advice to steer people away from mapReduce and toward aggregation pipelines.
These three pages look like likely entry points for mapReduce, so we may want to link to aggregation near the top:
In the mapReduce tutorial, "Various map-reduce operations can be rewritten".

Sorry, I was looking at the 4.2 docs instead of the upcoming 4.4 docs. I've tried to cross out everything that doesn't make sense or is already done. I guess what's left is only a suggestion to add those Note boxes to more pages, in case people land there directly from a link or search engine. |
