AWS documentdb documentation change

Service: documentdb · 2026-03-31 · Documentation low

File: documentdb/latest/developerguide/ne-aggregation.md

Summary

Added new documentation page for the $ne aggregation operator with examples in MongoDB Shell, Node.js, and Python

Security assessment

This change adds documentation for the $ne aggregation operator with standard code examples. The connection strings include TLS parameters (tls=true, tlsCAFile=global-bundle.pem) which are standard security practices for DocumentDB connections, but this is not introducing new security documentation - it's just showing standard connection parameters. No evidence of addressing a specific security vulnerability or incident.

+Example (MongoDB Shell)Code examples
+
+# $ne
+
+The `$ne` aggregation operator compares two values and returns `true` if they are not equal, otherwise returns `false`.
+
+**Parameters**
+
+  * `expression1`: The first value to compare.
+
+  * `expression2`: The second value to compare.
+
+
+
+
+## Example (MongoDB Shell)
+
+The following example demonstrates using the `$ne` operator to identify orders with status changes.
+
+**Create sample documents**
+    
+    
+    db.orders.insertMany([
+      { _id: 1, orderId: "A123", status: "shipped", expectedStatus: "shipped" },
+      { _id: 2, orderId: "B456", status: "pending", expectedStatus: "shipped" },
+      { _id: 3, orderId: "C789", status: "delivered", expectedStatus: "delivered" }
+    ]);
+
+**Query example**
+    
+    
+    db.orders.aggregate([
+      {
+        $project: {
+          orderId: 1,
+          status: 1,
+          expectedStatus: 1,
+          needsAttention: { $ne: ["$status", "$expectedStatus"] }
+        }
+      }
+    ]);
+
+**Output**
+    
+    
+    [
+      { _id: 1, orderId: 'A123', status: 'shipped', expectedStatus: 'shipped', needsAttention: false },
+      { _id: 2, orderId: 'B456', status: 'pending', expectedStatus: 'shipped', needsAttention: true },
+      { _id: 3, orderId: 'C789', status: 'delivered', expectedStatus: 'delivered', needsAttention: false }
+    ]
