AWS documentdb documentation change

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

File: documentdb/latest/developerguide/pull.md

Summary

Added new documentation page for the $pull operator in Amazon DocumentDB, including description, parameters, MongoDB shell example, and code examples in Node.js and Python

Security assessment

This is a routine documentation addition for a MongoDB operator ($pull) with standard usage examples. The code examples include TLS connection parameters (tls=true, tlsCAFile) which are standard security practices for DocumentDB connections, but this is not introducing new security documentation - it's just showing standard secure connection patterns that would be expected in any database connection example.

+
+# $pull
+
+The `$pull` operator is used to remove from an array all instances of a value or values that match a specified condition. This operator is useful when you need to remove specific elements from an array field within a document.
+
+**Parameters**
+
+  * `field`: The name of the array field from which to remove the value(s).
+
+  * `value`: The value or condition that determines which element(s) to remove from the array.
+
+
+
+
+## Example (MongoDB Shell)
+
+The following example demonstrates how to use the `$pull` operator to remove elements from an array field.
+
+**Create sample documents**
+    
+    
+    db.restaurants.insertMany([
+      {
+        name: "Pizza Hut",
+        cuisine: "Italian",
+        features: ["Delivery", "Takeout", "Dine-in"]
+      },
+      {
+        name: "Sushi Saito",
+        cuisine: "Japanese",
+        features: ["Dine-in", "Private Dining"]
+      },
+      {
+        name: "Taco Bell",
+        cuisine: "Mexican",
+        features: ["Delivery", "Takeout", "Drive-thru"]
+      }
+    ])
+
+**Query example**
+    
+    
+    db.restaurants.updateMany(
+      { cuisine: "Italian" },
+      { $pull: { features: "Takeout" } }
+    )
+
+**Output**
+    
+    
+    {
+      "acknowledged" : true,
+      "matchedCount" : 1,
+      "modifiedCount" : 1
+    }
+
+The above query removes the "Takeout" feature from all documents where the `cuisine` field is "Italian".
+

+
+Node.js
+    
+    
+    
+    const { MongoClient } = require('mongodb');
+    
+    async function updateRestaurants() {
+      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 restaurants = db.collection('restaurants');
+    
+      await restaurants.updateMany(
+        { cuisine: 'Italian' },
+        { $pull: { features: 'Takeout' } }
+      );
+    
+      const updatedRestaurants = await restaurants.find({}).toArray();
+      console.log(updatedRestaurants);
+    
+      await client.close();
+    }
+    
+    updateRestaurants();
+
+Python
+    
+    
+    
+    from pymongo import MongoClient
+    
+    def update_restaurants():
+        client = MongoClient('mongodb://<username>:<password>@<cluster-endpoint>:27017/?tls=true&tlsCAFile=global-bundle.pem&replicaSet=rs0&readPreference=secondaryPreferred&retryWrites=false')
+        db = client.test
+        restaurants = db.restaurants
+    
+        result = restaurants.update_many(
+            { 'cuisine': 'Italian' },
+            { '$pull': { 'features': 'Takeout' } }
+        )
+    
+        updated_restaurants = list(restaurants.find({}))
+        print(updated_restaurants)
+    
+        client.close()
+    
+    update_restaurants()
