AWS documentdb documentation change

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

File: documentdb/latest/developerguide/eq.md

Summary

Added new documentation page for the $eq query operator with examples in MongoDB Shell, Node.js, and Python, including connection strings with TLS configuration

Security assessment

The change adds documentation for a query operator and includes example connection strings that demonstrate security best practices (TLS=true, tlsCAFile parameter). This shows how to securely connect to DocumentDB but doesn't address a specific security vulnerability or incident.

+
+# $eq
+
+The `$eq` operator in Amazon DocumentDB is used to match documents where the value of a field is equal to the specified value. This operator is commonly used in the `find()` method to retrieve documents that meet the specified criteria.
+
+**Parameters**
+
+  * `field` : The field to check for the equality condition.
+
+  * `value` : The value to compare against the field.
+
+
+
+
+## Example (MongoDB Shell)
+
+The following example demonstrates the usage of the `$eq` operator to find all documents where the `name` field is equal to `"Thai Curry Palace"`.
+
+**Create sample documents**
+    
+    
+    db.restaurants.insertMany([
+      { name: "Thai Curry Palace", cuisine: "Thai", features: ["Private Dining"] },
+      { name: "Italian Bistro", cuisine: "Italian", features: ["Outdoor Seating"] },
+      { name: "Mexican Grill", cuisine: "Mexican", features: ["Takeout"] }
+    ]);
+
+**Query example**
+    
+    
+    db.restaurants.find({ name: { $eq: "Thai Curry Palace" } });
+
+**Output**
+    
+    
+    { "_id" : ObjectId("68ee586f916df9d39f3d9414"), "name" : "Thai Curry Palace", "cuisine" : "Thai", "features" : [ "Private Dining" ] }
+
+## Code examples

+
+Node.js
+    
+    
+    
+    const { MongoClient } = require('mongodb');
+    
+    async function findByName(name) {
+      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('restaurants');
+    
+      const results = await collection.find({ name: { $eq: name } }).toArray();
+      console.log(results);
+    
+      await client.close();
+    }
+    
+    findByName("Thai Curry Palace");
+
+Python
+    
+    
+    
+    from pymongo import MongoClient
+    
+    def find_by_name(name):
+        client = MongoClient("mongodb://<username>:<password>@<cluster-endpoint>:27017/?tls=true&tlsCAFile=global-bundle.pem&replicaSet=rs0&readPreference=secondaryPreferred&retryWrites=false")
+        db = client["test"]
+        collection = db["restaurants"]
+    
+        results = list(collection.find({ "name": { "$eq": name } }))
+        print(results)
+    
+        client.close()
+    
+    find_by_name("Thai Curry Palace")
