AWS documentdb documentation change

Service: documentdb · 2026-03-28 · Documentation low

File: documentdb/latest/developerguide/max.md

Summary

Entire documentation file for the $max aggregation stage was removed, including examples in MongoDB Shell, Node.js, and Python

Security assessment

This change removes documentation for a MongoDB aggregation operator ($max) but provides no indication of security issues. The removed content was standard documentation with code examples and no security warnings. This appears to be documentation reorganization rather than security-related changes.

-# $max
-
-The `$max` aggregation stage is used to return the maximum value of a specified field across all documents in a pipeline stage. This operator is useful for finding the highest value in a set of documents.
-
-**Parameters**
-
-  * `expression`: The expression to use to calculate the maximum value.
-
-
-
-
-## Example (MongoDB Shell)
-
-The following example demonstrates how to use the `$max` operator to find the maximum score in a collection of student documents. The `$group` stage groups all documents together, and the `$max` operator is used to calculate the maximum value of the `score` field across all documents.
-
-**Create sample documents**
-    
-    
-    db.students.insertMany([
-      { name: "John", score: 85 },
-      { name: "Jane", score: 92 },
-      { name: "Bob", score: 78 },
-      { name: "Alice", score: 90 }
-    ])
-
-**Query example**
-    
-    
-    db.students.aggregate([
-      { $group: { _id: null, maxScore: { $max: "$score" } } },
-      { $project: { _id: 0, maxScore: 1 } }
-    ])
-
-**Output**
-    
-    
-    [ { maxScore: 92 } ]

-
-Node.js
-    
-

-      const db = client.db('test');
-      const students = db.collection('students');
-    
-      const result = await students.aggregate([
-        { $group: { _id: null, maxScore: { $max: "$score" } } }
-      ]).toArray();
-    
-      console.log(result);
-      await client.close();
-    }
-    
-    findMaxScore();
