Are there additional exercises or courses on the Aggregation Framework that can help us practice and become more comfortable on topics such as $graphLookup, $lookup, $geoNear etc.
We are currently working on providing additional resources to our users so that they can get better understanding of aggregation framework.
Meanwhile, you can go through our documentation to explore more examples around these topics:
- More about Aggregation
- Aggregation Pipeline Stages
- Aggregation Pipeline Operators
Please let me know, if you have any questions.
