1
00:00:00,220 --> 00:00:01,700
‫Okay, so now let's talk about

2
00:00:01,700 --> 00:00:03,690
‫DynamoDB global tables.

3
00:00:03,690 --> 00:00:06,280
‫So this is a one feature need to know about for DynamoDB.

4
00:00:06,280 --> 00:00:08,370
‫It's a way for you to make DynamoDB table

5
00:00:08,370 --> 00:00:11,570
‫accessible with low latency and this is the key

6
00:00:11,570 --> 00:00:13,380
‫in multiple regions.

7
00:00:13,380 --> 00:00:14,350
‫So let's take an example.

8
00:00:14,350 --> 00:00:16,990
‫We have our DynamoDB table in us-east-one,

9
00:00:16,990 --> 00:00:18,920
‫and we'll set up as a global table.

10
00:00:18,920 --> 00:00:22,440
‫So the basics, of course, our users can do read and write

11
00:00:22,440 --> 00:00:26,220
‫to this DynamoDB table in Northern Virginia us-east-one.

12
00:00:26,220 --> 00:00:27,730
‫But it is possible for us

13
00:00:27,730 --> 00:00:30,800
‫to set up some replication for this global table.

14
00:00:30,800 --> 00:00:33,800
‫So we can create a global table in Paris eu-west-three

15
00:00:33,800 --> 00:00:34,900
‫and we'll say they're the same,

16
00:00:34,900 --> 00:00:37,240
‫so there's two way replication between these tables.

17
00:00:37,240 --> 00:00:40,190
‫That means that the same data is in us-east-one

18
00:00:40,190 --> 00:00:41,820
‫and in eu-west-three,

19
00:00:41,820 --> 00:00:45,000
‫but users, you know, there are close to the Paris region,

20
00:00:45,000 --> 00:00:48,730
‫can access this global table with low latency in Paris.

21
00:00:48,730 --> 00:00:52,420
‫So this is true for one to 10 regions, if you want it to.

22
00:00:52,420 --> 00:00:53,253
‫Okay.

23
00:00:53,253 --> 00:00:54,960
‫A global table is truly global

24
00:00:54,960 --> 00:00:56,500
‫and users can read and write

25
00:00:56,500 --> 00:00:58,750
‫to the table in any specific region,

26
00:00:58,750 --> 00:01:00,860
‫there will just be replication between these two.

27
00:01:00,860 --> 00:01:03,050
‫So the fact that there is read/write access

28
00:01:03,050 --> 00:01:05,780
‫to any region of AWS on this global table,

29
00:01:05,780 --> 00:01:08,400
‫makes it an active-active replication

30
00:01:08,400 --> 00:01:10,230
‫because you can actively write to any region

31
00:01:10,230 --> 00:01:13,590
‫and it will actively be replicated into other regions. Okay.

32
00:01:13,590 --> 00:01:15,600
‫So that's it, all you need to know for the exam.

33
00:01:15,600 --> 00:01:17,343
‫I will see you in the next session.
