AWS ... AWS Documentation AWS CloudFormation User Guide. For more information, see so we can do more of it. One of the big benefits of overloading your secondary index is that your provisioned capacity is shared across multiple use cases. The ease of creating and removing a global secondary index when a new query arises allows rapid development and reduces time to market. If you create multiple tables with indexes at the same time, You must specify the StreamSpecification property to use this Deploying a Lambda Function through CloudFormation. The AWS::DynamoDB::Table resource creates a DynamoDB table. serverless-plugin-dynamodb-autoscaling Autoscaling configuration for DynamoDB tables. AWS CloudFormation now supports Auto Scaling scheduled actions and DynamoDB local and global secondary indexes. Check out How To Create AWS DDB Secondary Indexes article to learn how to create secondary indexes. Global Secondary Indexes (GSI) DynamoDB creates and maintains indexes for the primary key attributes for efficient access of data in the table, which allows applications to quickly retrieve data by specifying primary key values. Javascript is disabled or is unavailable in your If you set BillingMode as PAY_PER_REQUEST, you cannot specify this property. One of the most important concepts to learn with DynamoDB is … Specify how you are charged for read and write throughput and how you manage capacity. Global secondary index is an index that have a partition key and an optional sort key that are different from base table’s primary key. But it's not at all clear how. When using global secondary indexes, you need to provision read and write capacity for each index separately from that of your base table. DynamoDB is a fully managed, fast, highly scalable, and flexible cloud database service for applications that need consistent, single-digit millisecond latency at any scale.
