            Unable to create DynamoDB table with LSI using dynamodb-data-mapper-js
            Asked 2019-Sep-19 at 06:44

            I'm trying to setup a DynamoDB database in Node.js using the official AWS library dynamodb-data-mapper-js to create persistent model objects and data mappers. However it looks like the don't mention anything about creating tables with Local Sencondary Indexes or either GSI.

            I found an issue in Github with a reference on how to create a table with LSI, the provided example explains the difference between referencing a rangeKey and declaring a LSI:

            ...

            ANSWER

            Answered 2019-Sep-19 at 06:44

            I found out the problem was that you need to specify some options about the type of index when you are creating the table. For example you need to at least specify if it's a LSI or GSI and which keys must the index include.

            Install dynamodb-data-mapper-js

            The @aws/dynamodb-data-mapper package provides a simple way to persist and load an application's domain objects to and from Amazon DynamoDB. When used together with the decorators provided by the @aws/dynamodb-data-mapper-annotations package, you can describe the relationship between a class and its representation in DynamoDB by adding a few decorators:.

            Support

            Using the mapper object and MyDomainObject class defined above, you can perform the following operations:. Creates (or overwrites) an item in the table. Retrieves an item from DynamoDB. NB: The promise returned by the mapper will be rejected with an ItemNotFoundException if the item sought is not found. Updates an item in the table. Removes an item from the table. Lists the items in a table or index. Finds a specific item (or range of items) in a table or index. The mapper also supports batch operations. Under the hood, the batch will automatically be split into chunks that fall within DynamoDB's limits (25 for batchPut and batchDelete, 100 for batchGet). The items can belong to any number of tables, and exponential backoff for unprocessed items is handled automatically. Creates (or overwrites) multiple items in the table. Fetches multiple items from the table. NB: Only items that exist in the table will be retrieved. If a key is not found, it will be omitted from the result. Removes multiple items from the table.
