1
00:00:00,500 --> 00:00:02,800
‫Now let's talk about DocumentDB.

2
00:00:02,800 --> 00:00:06,710
‫So the same way we had Aurora as the way for AWS

3
00:00:06,710 --> 00:00:09,310
‫to implement a sort of big cloud native version

4
00:00:09,310 --> 00:00:11,980
‫of PostgresSQL and MySQL,

5
00:00:11,980 --> 00:00:16,240
‫we have DocumentDB, which is an Aurora version for MongoDB.

6
00:00:16,240 --> 00:00:17,580
‫So MongoDB, if you don't know,

7
00:00:17,580 --> 00:00:19,680
‫that's the logo on the top right corner of your screen.

8
00:00:19,680 --> 00:00:21,870
‫It is another NoSQL database,

9
00:00:21,870 --> 00:00:23,340
‫and you need to remember this for the exam.

10
00:00:23,340 --> 00:00:25,820
‫So DocumentDB is a NoSQL database,

11
00:00:25,820 --> 00:00:29,960
‫and it's based on top of the MongoDB technology.

12
00:00:29,960 --> 00:00:31,560
‫So it's compatible with MongoDB.

13
00:00:31,560 --> 00:00:36,560
‫So MongoDB is used to store query and index JSON data,

14
00:00:36,910 --> 00:00:39,970
‫and you have the same similar deployment concept

15
00:00:39,970 --> 00:00:41,230
‫as Aurora with DocumentDB.

16
00:00:41,230 --> 00:00:43,300
‫So that means it's a fully managed database.

17
00:00:43,300 --> 00:00:44,680
‫It's highly available.

18
00:00:44,680 --> 00:00:48,070
‫Data is replicated across three availability zones,

19
00:00:48,070 --> 00:00:50,140
‫and the storage will grow automatically

20
00:00:50,140 --> 00:00:51,970
‫in increments of 10 gigabytes

21
00:00:51,970 --> 00:00:54,930
‫up to 64 terabytes of storage, all of this, okay?

22
00:00:54,930 --> 00:00:57,660
‫And DocumentDB has been engineered so it's can scale

23
00:00:57,660 --> 00:01:01,030
‫to workloads with millions of requests per second.

24
00:01:01,030 --> 00:01:05,010
‫So at the exam, if you see anything related to MongoDB,

25
00:01:05,010 --> 00:01:07,730
‫think DocumentDB, or if you see anything related

26
00:01:07,730 --> 00:01:12,730
‫to NoSQL databases, think DocumentDB and also DynamoDB.

27
00:01:13,630 --> 00:01:14,670
‫That's it for this lecture.

28
00:01:14,670 --> 00:01:15,503
‫I hope you liked it,

29
00:01:15,503 --> 00:01:17,440
‫and I will see you in the next lecture.
