Summary

Entire documentation page for the $ltrim operator in Amazon DocumentDB has been removed, including all content, examples, and code samples

Security assessment

This change removes an entire documentation page about the $ltrim operator (a string manipulation function). There is no evidence in the diff that this removal is related to a security vulnerability, weakness, or incident. The removal appears to be a documentation restructuring or deprecation of content, not a security-related change. The content removed was purely functional documentation about a MongoDB operator implementation in DocumentDB.

-# $ltrim
-
-New from version 4.0.
-
-Not supported by Elastic cluster.
-
-The `$ltrim` operator in Amazon DocumentDB is used to remove leading characters from a string. By default, it removes leading whitespace characters, but you can also specify a set of characters to remove by passing the chars argument.
-
-**Parameters**
-
-  * `input`: The input string from which to remove leading whitespace characters.
-
-  * `chars`: (optional) To remove specific characters.
-
-
-
-
-## Example (MongoDB Shell)
-
-The following example demonstrates the usage of `$ltrim` to remove specified characters (" *") from the beginning of a string.
-
-**Create sample documents**
-    
-    
-    db.collection.insertMany([
-      { name: " *John Doe", age: 30 },
-      { name: "Jane Doe*", age: 25 },
-      { name: "  Bob Smith  ", age: 35 }
-    ]);
-
-**Query example**
-    
-    
-    db.collection.aggregate([
-      {
-        $project: {
-          _id: 0,
-          name: {
-            $ltrim: { input: "$name", chars: " *" }  
-          },
-          age: 1
-        }
-      }
-    ]);
-
-**Output**
-    
-    
-    [
-      { "name": "John Doe", "age": 30 },
-      { "name": "Jane Doe ", "age": 25 },
-      { "name": "Bob Smith  ", "age": 35 }
-    ]
