Lavora con le tabelle globali di DynamoDB e la replica multiregionale utilizzando v2 AWS Command Line Interface

Crea una tabella con replica multiregionale.

# Step 1: Create a new table in us-west-2
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-west-2

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

Descrivi la tabella multiregionale.

# Describe the base table
aws dynamodb describe-table --table-name MusicTable --region us-west-2

Inserisci gli elementi in una tabella di replica.

# Write a single item to one of the replica tables.
aws dynamodb put-item \
    --table-name MusicTable \
    --item '{"Artist": {"S":"item_1"},"SongTitle": {"S":"Song Value 1"}}' \
    --region us-east-2

Ottieni elementi dalle tabelle di replica.

# Get item from the other two replicas
aws dynamodb get-item \
    --table-name MusicTable \
    --key '{"Artist": {"S":"item_1"},"SongTitle": {"S":"Song Value 1"}}' \
    --consistent-read \
    --region us-east-1

aws dynamodb get-item \
    --table-name MusicTable \
    --key '{"Artist": {"S":"item_1"},"SongTitle": {"S":"Song Value 1"}}' \
    --consistent-read \
    --region us-west-2

Rimuovi le repliche.

# Remove the replica tables.
aws dynamodb update-table \
    --table-name MusicTable \
    --replica-updates '[{"Delete": {"RegionName": "us-east-2"}}, {"Delete": {"RegionName": "us-east-1"}}]' \
    --region us-west-2
