AWS documentdb documentation change
Summary
Entire documentation page for the $dateToString aggregation operator was removed, including all content, examples, and code samples
Security assessment
This change removes documentation for a date formatting function in Amazon DocumentDB. There is no evidence in the diff that this removal is related to a security vulnerability or incident. The removed content appears to be standard documentation for a MongoDB aggregation operator with no security-specific content. This appears to be routine documentation maintenance, restructuring, or deprecation rather than a security-related change.

This is useful when you need to format the date and time in a specific way for display or further processing. - -**Parameters** - - * `date`: The date or timestamp value to be converted to a string. - - * `format`: A string that specifies the format in which the date should be represented. The format string can include various format specifiers, such as `%Y` for the four-digit year, `%m` for the two-digit month, `%d` for the two-digit day of the month, etc. - - * `timezone`: (optional) The time zone to use for the conversion. If not specified, the time zone of the server hosting the Amazon DocumentDB cluster is used. - - * `onNull`: (optional) The value to be returned if the `date` parameter is `null`. - - - - -## Example (MongoDB Shell) - -The following example demonstrates the usage of the `$dateToString` operator to format the `logDate` field of the `missionLog` collection. - -**Create sample documents** - - - db.missionLog.insertMany([ - { _id: 1, "event":"missionStart", logDate: new Date("2020-03-15T13:41:33Z") }, - { _id: 2, "event":"jumpPoint1", logDate: new Date("2020-03-15T13:45:34Z") }, - { _id: 3, "event":"jumpPoint2", logDate: new Date("2020-03-15T13:48:21Z") }, - { _id: 4, "event":"jumpPoint3", logDate: new Date("2020-03-15T13:52:09Z") }, - { _id: 5, "event":"missionEnd", logDate: new Date("2020-03-15T13:58:44Z") } - ]); - -**Query example** - - - db.missionLog.aggregate([ - { - $project: { - event: "$event", - logDateFormatted: { - $dateToString: { - format: "%Y-%m-%d %H:%M:%S", - date: "$logDate" - } - } - } - } - ]) - -**Output** - - - [ - { - "_id": 1, - "event": "missionStart", - "logDateFormatted": "2020-03-15 13:41:33" - }, - { - "_id": 2, - "event": "jumpPoint1", - "logDateFormatted": "2020-03-15 13:45:34" - }, - { - "_id": 3, - "event": "jumpPoint2", - "logDateFormatted": "2020-03-15 13:48:21" - }, - { - "_id": 4, - "event": "jumpPoint3", - "logDateFormatted": "2020-03-15 13:52:09" - }, - { - "_id": 5, - "event": "missionEnd", - "logDateFormatted": "2020-03-15 13:58:44" - } - ] - -## Code examples - -To view a code example for using the `$dateToString` command, choose the tab for the language that you want to use: - -Node.js - - -Here's an example of using the `$dateToString` 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('missionLog'); - - const result = await collection.aggregate([ - { - $project: { - event: "$event", - logDateFormatted: { - $dateToString: { - format: "%Y-%m-%d %H:%M:%S", - date: "$logDate" - } - } - } - } - ]).toArray(); - - console.log(result); - await client.close(); - } - - example(); - -Python - - -Here's an example of using the `$dateToString` operator in a Python application: - - - from pymongo import MongoClient - - def example(): - client = MongoClient('mongodb://<username>:<password>@<cluster-endpoint>:27017/?tls=true&tlsCAFile=global-bundle.pem&replicaSet=rs0&readPreference=secondaryPreferred&retryWrites=false') - db = client['test'] - collection = db['missionLog'] - - pipeline = [ - { - '$project': { - 'event': '$event', - 'logDateFormatted': { - '$dateToString': { - 'format': '%Y-%m-%d %H:%M:%S', - 'date': '$logDate' - } - } - } - } - ] - - result = list(collection.aggregate(pipeline)) - print(result) - client.close() - - example() - - **Javascript is disabled or is unavailable in your browser.** - -To use the Amazon Web Services Documentation, Javascript must be enabled.
