Tutorial: Creating MRSC global tables in DynamoDB

Sign in to the AWS Management Console and open the DynamoDB console at https://console.aws.amazon.com/dynamodb/.

From the top navigation pane, choose the Region where global tables with MRSC is supported. For example, choose us-east-2.

Create a new on-demand, single-Region table. For information about creating a table, see AWS Management Console in Step 1: Create a table in DynamoDB.

On the Tables page, choose your newly created table.

Choose the Global tables tab, then choose Create replica.

On the Create replica page, do the following:

1. Under Multi-Region Consistency, choose Strong consistency.

2. Choose Create replicas.

Create a new on-demand, single-Region table named MusicTable in the us-east-2 Region.

aws dynamodb create-table \
    --table-name MusicTable \
    --attribute-definitions \
        AttributeName=Artist,AttributeType=S \
        AttributeName=SongTitle,AttributeType=S \
    --key-schema \
        AttributeName=Artist,KeyType=HASH \
        AttributeName=SongTitle,KeyType=RANGE \
    --billing-mode PAY_PER_REQUEST \
    --region us-east-2

Verify that the new table has been created and is in the ACTIVE state.

aws dynamodb describe-table \
    --table-name MusicTable \
    --region us-east-2
    
    {
    "Table": {
        ...
        "TableStatus": "ACTIVE",
       ...
}

Add two new replica tables to the single-Region table in the remaining supported Regions for preview by specifying the multi-region-consistency parameter to STRONG.

aws dynamodb update-table \
    --table-name MusicTable \
    --replica-updates '[{"Create": {"RegionName": "us-east-1"}}, {"Create": {"RegionName": "us-west-2"}}]' \
    --multi-region-consistency STRONG \
    --region us-east-2

Use the describe-table command to verify that the two new replicas have been created and are in the ACTIVE state, and that the global table is configured for multi-Region strong consistency.

aws dynamodb describe-table \
    --table-name MusicTable \
    --region us-east-1
    
    {
    "Table": {
        ...
        "Replicas": [
            {
                "RegionName": "us-east-1",
                "ReplicaStatus": "ACTIVE"
            },
            {
                "RegionName": "us-west-2",
                "ReplicaStatus": "ACTIVE"
            }
        ],
        "MultiRegionConsistency": "STRONG"
       ...
}
