Learn MongoDb Aggregation 2024
This video tutorial guides you through a MongoDB aggregation pipeline to retrieve posts containing the top 3 most frequently used tags.
We'll break down the steps involved:
Unwind the Tags Array:
We'll use the $unwind operator to separate each tag from the tags array within each post document.
Group by Tags and Count:
Using the $group operator, we'll group documents by tags and create a count for each unique tag.
Push Titles into an Array:
We'll create an array to store the titles of posts containing each tag using the $push accumulator.
Sort by Count (Descending):
The $sort operator arranges the results in descending order based on the count (most popular tags first).
Limit to Top 3:
We'll use the $limit operator to restrict the output to only the top 3 tags.
Project and Rename Fields :
Finally, the $project operator allows you to display the desired output format, including renaming the _id field to "tags" for better readability.
By following these steps, you'll be able to efficiently query your MongoDB database to find posts associated with the most popular tags.
