lambda function to query DynamoDB present in another region?

I am wondering if we can write a lambda function in one region for example us-east-1 to query a DynamoDB database present in another region.

I feel that there is a provision. just wondering how the syntax would be to achieve this.

dynamo_client = boto3.resource('dynamodb')
dynamo_table = dynamo_client.Table('table')

Above is a normal example of a dynamodb connection in the same region.

Wondering how would be the syntax when we want to access the dynamodb from another region.

Thank you

Yes you can. In your Lambda code - you can still set the Region for the DynamoDB Service Client. Consider this Java example:

// Create a DynamoDbClient object
 Region region = Region.US_WEST_2;
 DynamoDbClient ddb = DynamoDbClient.builder()
            .region(region)
            .build();

Now you can interact with a DynamoDB table located in US-WEST_2 region.

Yes, you can. resource takes region_name parameter:

dynamo_client = boto3.resource('dynamodb', region_name='<your-other-regio>')
dynamo_table = dynamo_client.Table('table')
