‫Okay, so now let's talk about
‫DynamoDB global tables.
‫So this is a one feature need to know about for DynamoDB.
‫It's a way for you to make DynamoDB table
‫accessible with low latency and this is the key
‫in multiple regions.
‫So let's take an example.
‫We have our DynamoDB table in us-east-one,
‫and we'll set up as a global table.
‫So the basics, of course, our users can do read and write
‫to this DynamoDB table in Northern Virginia us-east-one.
‫But it is possible for us
‫to set up some replication for this global table.
‫So we can create a global table in Paris eu-west-three
‫and we'll say they're the same,
‫so there's two way replication between these tables.
‫That means that the same data is in us-east-one
‫and in eu-west-three,
‫but users, you know, there are close to the Paris region,
‫can access this global table with low latency in Paris.
‫So this is true for one to 10 regions, if you want it to.
‫Okay.
‫A global table is truly global
‫and users can read and write
‫to the table in any specific region,
‫there will just be replication between these two.
‫So the fact that there is read/write access
‫to any region of AWS on this global table,
‫makes it an active-active replication
‫because you can actively write to any region
‫and it will actively be replicated into other regions. Okay.
‫So that's it, all you need to know for the exam.
‫I will see you in the next session.
