Hey! ICYMI - starting in the Java driver v4.9 and later, we’ve introduced a simpler way to construct aggregation expressions, by using Builders for Aggregation Expressions. If you’re new to Builders, they allow you to use the power of the IDE to catch errors early on, and to discover new methods. To get started using Builders for Aggregation Expressions, check out the documentation here.
We’ve also got a tutorial!
If you’ve already given this feature a try, I’d love to know what you think. Drop a reply to this post with your feedback or thoughts.
