IAM policy to read, write, update, and delete access on a DynamoDB table

Use this policy if you need to allow your application to create, read, update, and delete data in Amazon DynamoDB tables, indexes, and streams. Substitute the Amazon Region name, your account ID, and the table name or wildcard character (*) where appropriate.

{ "Version": "2012-10-17", "Statement": [ { "Sid": "DynamoDBIndexAndStreamAccess", "Effect": "Allow", "Action": [ "dynamodb:GetShardIterator", "dynamodb:Scan", "dynamodb:Query", "dynamodb:DescribeStream", "dynamodb:GetRecords", "dynamodb:ListStreams" ], "Resource": [ "arn:aws:dynamodb:us-west-2:123456789012:table/Books/index/*", "arn:aws:dynamodb:us-west-2:123456789012:table/Books/stream/*" ] }, { "Sid": "DynamoDBTableAccess", "Effect": "Allow", "Action": [ "dynamodb:BatchGetItem", "dynamodb:BatchWriteItem", "dynamodb:ConditionCheckItem", "dynamodb:PutItem", "dynamodb:DescribeTable", "dynamodb:DeleteItem", "dynamodb:GetItem", "dynamodb:Scan", "dynamodb:Query", "dynamodb:UpdateItem" ], "Resource": "arn:aws:dynamodb:us-west-2:123456789012:table/Books" }, { "Sid": "DynamoDBDescribeLimitsAccess", "Effect": "Allow", "Action": "dynamodb:DescribeLimits", "Resource": [ "arn:aws:dynamodb:us-west-2:123456789012:table/Books", "arn:aws:dynamodb:us-west-2:123456789012:table/Books/index/*" ] } ] }

To expand this policy to cover all DynamoDB tables in all Amazon Regions for this account, use a wildcard (*) for the Region and table name. For example:

"Resource":[ "arn:aws:dynamodb:*:123456789012:table/*/", "arn:aws:dynamodb:*:123456789012:table/*/index/*" ]
