AWS documentdb documentation change

Summary

Added comprehensive documentation for the $pow operator in Amazon DocumentDB, including introduction, parameters, MongoDB Shell example, and code examples in Node.js and Python with connection details

Security assessment

This change adds documentation for a mathematical operator ($pow) in Amazon DocumentDB's aggregation framework. The documentation includes standard connection examples with TLS parameters, but there is no evidence of addressing a specific security vulnerability or weakness. The TLS parameters shown are standard security best practices for DocumentDB connections, not new security features or fixes.

+# $pow
+
+Introduced in 8.0
+
+The `$pow` operator in Amazon DocumentDB allows you to raise a number to a power. This can be useful for performing exponential calculations within your aggregation pipeline.
+
+**Parameters**
+
+  * `<number>` (required): The number to be raised to a power.
+
+  * `<exponent>` (required): The power to which the number should be raised.
+
+
+
+
+## Example (MongoDB Shell)
+
+The following example demonstrates how to use the `$pow` operator to calculate the square of a number.
+
+**Create sample documents**
+    
+    
+    db.numbers.insertMany([
+      { "_id": 1, "value": 2 },
+      { "_id": 2, "value": 3 },
+      { "_id": 3, "value": 4 }
+    ]);
+
+**Query example**
+    
+    
+    db.numbers.aggregate([
+      { $addFields: { "square": { $pow: ["$value", 2] } } }
+    ])
+
+**Output**
+    
+    
+    [
+      { "_id": 1, "value": 2, "square": 4 },
+      { "_id": 2, "value": 3, "square": 9 },
+      { "_id": 3, "value": 4, "square": 16 }
+    ]
+
+## Code examples
+
+To view a code example for using the `$pow` command, choose the tab for the language that you want to use:
+
+Node.js
+    
+
+Here's an example of using the $pow operator in a Node.js application:
+    
+    
+    const { MongoClient } = require('mongodb');
+    
+    async function example() {
+      const client = await MongoClient.connect('mongodb://<username>:<password>@<cluster-endpoint>:27017/?tls=true&tlsCAFile=global-bundle.pem&replicaSet=rs0&readPreference=secondaryPreferred&retryWrites=false');
+      const db = client.db('test');
+      const collection = db.collection('numbers');
+    
+      const result = await collection.aggregate([
+        { $addFields: { "square": { $pow: ["$value", 2] } } }
+      ]).toArray();
+    
+      console.log(result);
+      await client.close();
+    }
+    
+    example();
+
+Python
+    
+
+Here's an example of using the $pow operator in a Python application:
+    
+    
+    from pymongo import MongoClient
+    
+    def example():
+        client = MongoClient('mongodb://<username>:<password>@<cluster-endpoint>:27017/?tls=true&tlsCAFile=global-bundle.pem&replicaSet=rs0&readPreference=secondaryPreferred&retryWrites=false')
+        db = client['test']
+        collection = db['numbers']
+    
+        result = list(collection.aggregate([
+            { "$addFields": { "square": { "$pow": ["$value", 2] } } }
+        ]))
+    
+        print(result)
+        client.close()
+    
+    example()
