How to add a column in dynamodb?

To add a column in a DynamoDB table, you need to follow these steps:

1. Access the AWS Management Console and navigate to the DynamoDB service.
2. Select the table in which you want to add a column.
3. Click on the "Items" tab to view the items in the table.
4. Click on the "Actions" dropdown menu and select "Edit Items."
5. In the edit items window, click on the "+" button to add a new column.
6. Enter the name of the new column and provide a value for the new column in one or more items.
7. Click on the "Save" button to save the changes.

Alternatively, you can also add a new column programmatically using AWS SDKs or AWS CLI. Here is an example using AWS CLI:

aws dynamodb update-table --table-name YourTableName --attribute-definitions AttributeName=NewColumn,AttributeType=S --global-secondary-index-updates 'Create={IndexName=NewColumnIndex,KeySchema=[{AttributeName=NewColumn,KeyType=HASH}],ProvisionedThroughput={ReadCapacityUnits=5,WriteCapacityUnits=5}}'

Replace YourTableName with the name of your DynamoDB table, NewColumn with the name of the new column, and NewColumnIndex with the name of the global secondary index.

After running this command, the new column will be added to your DynamoDB table.
