Amazon DynamoDB table w/ Elastic Beanstalk not setting up correct parameters

Question

I have an example Dynamodb project from Amazon that when uploaded to an instance of Elastic Beanstalk environment, generates a Dynamodb table. Howevever, after generating the table is missing a few parameters.

Here is the code to the Elastic Beanstalk instance:

                                .withProjection(new Projection().withProjectionType(ProjectionType.ALL)));

        return createTableRequest;
    }
}

Which should create a table with these parameters: HashKey RangeKey Geohash BuruMsg

and range/hash indices of: Geohash and HashKey

However my table only constructs with Hash, Range and geohash. It never adds my BuruMsg attribute.

Any ideas?

Edit:

Here is a picture of me attempting to insert an item into the database on AWS Console.

Answer 1

The schema of DynamoDB tables only specifies the hash key, optional range key, and optional index keys. The schema does not cover attribute fields that are uninvolved in a key or index. I believe that is why your BuruMsg field does not appear in the management console UI. You can certainly put data to that field, and you will observe it in the item listing in the management console.

But defining attributes is helpful to client software, such as the Java and .NET ORM libraries. There may be nothing wrong with your code.
